文章由来：公司有个实习同学需要做毕业设计，不会搭建环境，我就代劳了，顺便分享给刚入门的小伙伴，我是自学的JAVA，所以我懂的....
（大图直接观看显示很模糊，请在图片上点击右键然后在新窗口打开看）
先看下项目的整体层次结构及说明，本次是用的web3.0，所以需要tomcat8及以上才能运行
再看下用到了哪些jar包，jar包可以说是最精简的了，采用的maven管理
测试：请求地址时，会增加一条数据到数据库，然后读出所有数据，仅供演示，就没再分开了。
我提供了两种方式，一种是返回结果并展示到jsp页面，用到了jstl；另一种就是直接返回的json
先看返回到jsp页面的：
代码如下：
package com.xiaochangwei.web.controller;
import java.util.UUID;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import com.xiaochangwei.web.beans.User;
import com.xiaochangwei.web.service.TestService;
/**
* @since 2017年1月5日 上午9:33:48
* @author 肖昌伟 317409898@qq.com
* @description
*/
@Controller
@RequestMapping("jsp")
public class TestJspController {
private static final Logger LOGGER = LoggerFactory.getLogger(TestJspController.class);
@Autowired
private TestService testService;
@RequestMapping(value = "user", method = { RequestMethod.GET, RequestMethod.POST })
public ModelAndView jsp(ModelAndView mv) {
LOGGER.info("测试增加并返回用户列表到jsp");
User addUser = new User();
addUser.setUsername(UUID.randomUUID().toString());
addUser.setPassword(String.valueOf(System.currentTimeMillis()));
mv.addObject("users", testService.testAdd(addUser));
mv.setViewName("userList");
return mv;
}
}
再看直接返回json数据的：
代码如下：
package com.xiaochangwei.web.controller;
import java.util.List;
import java.util.UUID;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.xiaochangwei.web.beans.User;
import com.xiaochangwei.web.service.TestService;
/**
* @since 2017年1月5日 上午9:36:53
* @author 肖昌伟 317409898@qq.com
* @description
*/
@RestController
@RequestMapping("json")
public class TestJsonController {
private static final Logger LOGGER = LoggerFactory.getLogger(TestJsonController.class);
@Autowired
private TestService testService;
@RequestMapping(value = "user", method = { RequestMethod.GET, RequestMethod.POST })
public List<User> json() {
LOGGER.info("测试增加并返回用户列表到JSON");
User addUser = new User();
addUser.setUsername(UUID.randomUUID().toString());
addUser.setPassword(String.valueOf(System.currentTimeMillis()));
return testService.testAdd(addUser);
}
}
其实就只是RestController 和 Controller的区别，查看源码你会发现，其实RestController就是在Controller上面加了一个用于返回JSON的ResponseBody
看看web.xml 由于是采用的web 3.0 所以注意最开始的部分
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1"> <display-name>springmvctest</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:/springConfig/applicationContext-*.xml</param-value> </context-param> <!-- 统一编码 --> <filter> <filter-name>charsetEncoding</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>charsetEncoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 自动装配配置信息 地址由上面的contextConfigLocation指定 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 解决java.beans.Introspector导致的内存泄漏的问题 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- druid自带的sql操作监控 --> <servlet> <servlet-name>DruidStatView</servlet-name> <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>DruidStatView</servlet-name> <url-pattern>/druid/*</url-pattern> </servlet-mapping> <!-- 前端控制器 --> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 默认加载/WEB-INF/[servlet-name]-servlet.xml,通过下面的contextConfigLocation修改 --> <init-param> <param-name>contextConfigLocation</param-name> <param-value> classpath:spring-mvc.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
再看看pom文件
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.xiaochangwei.web</groupId> <artifactId>web-demo</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>web-demo Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <maven.compiler.encoding>UTF-8</maven.compiler.encoding> <compiler.version>1.7</compiler.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> <!-- spring 4.3.5--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.3.5.RELEASE</version> <!-- 会自动加载关联的 aop、beans、context、expression、core、commons-logging 这几个jar --> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.3.5.RELEASE</version> </dependency> <!-- 返回json结果时，如使用了restController或者responseBody --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.8.5</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.8.5</version> <!-- 会自动加载jackson-annotations --> </dependency> <!-- 文件上传 --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.2</version> <!-- 会自动加载commons-io --> </dependency> <!-- 日志记录 --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.22</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.22</version> <!-- 会自动加载log4j --> </dependency> <!-- 通过mybatis操作mysql数据库 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.3.5.RELEASE</version> <!-- 自动加载spring-tx --> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.0</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.1</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.27</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.40</version> </dependency> <!-- jsp页面标签 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 对象与JSON串相互转换 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.23</version> </dependency> </dependencies> <build> <finalName>web-demo</finalName> <resources> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.properties</include> </includes> </resource> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.xml</include> </includes> </resource> </resources> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>3.1</version> <configuration> <source>${compiler.version}</source> <target>${compiler.version}</target> <encoding>utf-8</encoding> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>2.1.1</version> <configuration> <archive> <addMavenDescriptor>false</addMavenDescriptor> </archive> <warName>web-demo</warName> <webResources> <resource> <directory>src/main/resources</directory> <targetPath>WEB-INF/classes</targetPath> <filtering>true</filtering> </resource> </webResources> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <configuration> <skip>true</skip> <testFailureIgnore>true</testFailureIgnore> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-enforcer-plugin</artifactId> <version>1.4.1</version> <executions> <execution> <id>enforce</id> <configuration> <rules> <dependencyConvergence /> </rules> </configuration> <goals> <goal>enforce</goal> </goals> </execution> </executions> </plugin> </plugins> </build> </project>
再看看重要的spring-mvc.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:task="http://www.springframework.org/schema/task" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.3.xsd"> <!-- 扫描路径 --> <context:component-scan base-package="com.xiaochangwei.web"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan> <!-- 配置根视图 --> <mvc:view-controller path="/" view-name="index" /> <!-- 激活基于注解的配置 --> <mvc:annotation-driven> <!-- json返回时默认的转换器，如果不需要返回json結果，可以不用配置 --> <mvc:message-converters register-defaults="true"> <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"></bean> </mvc:message-converters> </mvc:annotation-driven> <!-- 静态资源配置 --> <mvc:resources location="/assets/" mapping="/assets/**"></mvc:resources> <!-- 视图层配置 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/pages/" /> <property name="suffix" value=".jsp" /> </bean> <!-- 文件上传大小限定，如果项目中没有文件上传功能可以不用配置 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="maxUploadSize" value="10485760" /> </bean> </beans>
如果希望返回的json数据中日期能按照某种格式显示，可以这样配置：
<mvc:annotation-driven> <!-- 处理responseBody 里面日期类型 --> <mvc:message-converters> <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name="objectMapper"> <bean class="com.fasterxml.jackson.databind.ObjectMapper"> <property name="dateFormat"> <bean class="java.text.SimpleDateFormat"> <constructor-arg type="java.lang.String" value="yyyy-MM-dd HH:mm:ss" /> </bean> </property> </bean> </property> </bean> </mvc:message-converters> </mvc:annotation-driven>
上面这样配置是全局的时间格式显示，如果想对某些Date类型的设置其他格式，可以在字段上方增加
@JsonFormat(pattern="yyyy-MM-dd",timezone = "GMT+8") private Date lastAccessTime;
继续看数据源的配置、事物、mybatis的扫描路径配置 applicationContext-db.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <property name="url" value="${datasource.read.url}" /> <property name="username" value="${datasource.read.username}" /> <property name="password" value="${datasource.read.password}" /> <property name="initialSize" value="${datasource.initial.size}" /> <property name="maxActive" value="${datasource.max.size}" /> <property name="minIdle" value="${datasource.min.idle}" /> <property name="maxWait" value="60000" /> <property name="poolPreparedStatements" value="false" /> <property name="validationQuery" value="${datasource.validation.query}" /> <property name="testOnBorrow" value="false" /> <property name="testOnReturn" value="false" /> <property name="testWhileIdle" value="true" /> <property name="timeBetweenEvictionRunsMillis" value="60000" /> <property name="minEvictableIdleTimeMillis" value="300000" /> <property name="removeAbandoned" value="true" /> <property name="removeAbandonedTimeout" value="1800" /> <property name="logAbandoned" value="true" /> <property name="filters" value="stat" /> <property name="proxyFilters"> <list> <bean class="com.alibaba.druid.filter.logging.Log4jFilter"> <property name="statementExecutableSqlLogEnable" value="true" /> </bean> </list> </property> </bean> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="configLocation" value="classpath:mybatis-config.xml" /> <property name="mapperLocations"> <list> <value>classpath:mybatisMapper/*.xml</value> </list> </property> <!-- 读写分离插件 --> <!-- <property name="plugins"> --> <!-- <array> --> <!-- <bean class="com.xiaochangwei.web.interceptor.MybatisRWSplitInterceptor" /> --> <!-- </array> --> <!-- </property> --> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.xiaochangwei.web.dao" /> </bean> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true" /> </beans>
资源的加载，单独列出来了，可以合并到一起
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <!-- 加载所有的properties文件 --> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <value>classpath:*.properties</value> </list> </property> </bean> </beans>
mybatis的配置，别名这些扫描等， 不太明白的可以下载mybatis源码下来仔细看看，其实mybatis的实现真的很简单
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <settings> <setting name="lazyLoadingEnabled" value="false" /> <setting name="cacheEnabled" value="false" /> <setting name="logImpl" value="STDOUT_LOGGING" /> </settings> <typeAliases> <package name="com.xiaochangwei.web.beans" /> <package name="com.xiaochangwei.web.vo" /> </typeAliases> </configuration>
另外就是jdbc的信息了
#configuration datasource datasource.read.url=jdbc:mysql://xiaochangwei.com:3306/test?autoReconnect=true&useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull datasource.read.username=root datasource.read.password=123456 datasource.initial.size=5 datasource.max.size=10 datasource.min.idle=0 datasource.validation.query=select 1
这里需要提醒的是，url后面的编码还有最后的zeroDateTimeBehavior=convertToNull不要写漏了，某些条件下意义非常重大，曾经我负责的项目因为少写了这个出现了异常的 教训
然后就是mapper了
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN" "http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd"> <mapper namespace="com.xiaochangwei.web.dao.TestDao"> <select id="getAll" resultType="user"> SELECT id,username,password FROM t_user </select> <insert id="testInsert" parameterType="user" useGeneratedKeys="true" keyProperty="id"> INSERT INTO t_user(username,password) VALUES (#{username}, #{password}) </insert> </mapper>
日志配置也顺便贴出来

log4j.appender.L=org.apache.log4j.DailyRollingFileAppender
log4j.appender.L.File=C:\xiao-web-demo.log

日志真的很重要，尤其是mybatis的sql相关的，在开发阶段起了很大作用，下面是我本地的日志输出
