Spring+Druid+SpringMVC的搭建（附Demo）

最近公司事情比较少，便想利用这段空闲时间做一个自己的博客。

前端界面已经搞好，感谢杨姐的模板，自己稍微把模板没有的模块给补全了。

今天便开始自己的SSM框架搭建，数据库链接是采用数据库连接池。先上个项目结构图：

这个是基于Maven搭建的ssm框架，我把service层删除了，去掉了dao层接口，业务在需要与数据库交互的时候便直接调用dao层的方法。

1、创建maven项目，maven没有接触过的请自行百度 maven项目在eclisp如何创建。

2、配置 pom.xml 加载jar包

3、在src/main/java跟目录下建好需要的包

4、在src/main/resource下创建spring-mvc.xml

 1 <?xml version="1.0" encoding="UTF-8"?>  
 2 <beans xmlns="http://www.springframework.org/schema/beans"  
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"  
 4     xmlns:context="http://www.springframework.org/schema/context"  
 5     xmlns:mvc="http://www.springframework.org/schema/mvc"  
 6     xsi:schemaLocation="http://www.springframework.org/schema/beans    
 7                         http://www.springframework.org/schema/beans/spring-beans-3.1.xsd    
 8                         http://www.springframework.org/schema/context    
 9                         http://www.springframework.org/schema/context/spring-context-3.1.xsd    
10                         http://www.springframework.org/schema/mvc    
11                         http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">  
12     <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->  
13     <context:component-scan base-package="com.cwj.controller" />  
14     <!-- 扩充了注解驱动，可以将请求参数绑定到控制器参数 -->
15     <mvc:annotation-driven/>
16     
17     <!-- 静态文件处理  -->
18     <!-- location:表示/assets/目录下（即服务器根目录）的static包下的所有文件 -->
19     <!-- mapping:表示以/static开头的所有请求路径，如/static/a 或者/static/a/b -->
20     <mvc:resources location="/assets/" mapping="/public/**/" />
21     
22     <!--避免IE执行AJAX时，返回JSON出现下载文件 -->  
23     <bean id="mappingJacksonHttpMessageConverter"  
24         class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">  
25         <property name="supportedMediaTypes">

30     </bean>  
31     <!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 -->  
32     <bean

40       
41     <!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 -->  
42     <bean id="multipartResolver"    
43         class="org.springframework.web.multipart.commons.CommonsMultipartResolver">    
44         <!-- 默认编码 -->  
45         <property name="defaultEncoding" value="utf-8" />    
46         <!-- 文件大小最大值 -->  
47         <property name="maxUploadSize" value="10485760000" />    
48         <!-- 内存中的最大值 -->  
49         <property name="maxInMemorySize" value="40960" />    
50         <!-- 启用是为了推迟文件解析，以便捕获文件大小异常 -->
51         <property name="resolveLazily" value="true"/>
52     </bean>   
53     
54     <!-- 配置ViewResolver 。可用多个ViewResolver 。使用order属性排序。   InternalResourceViewResolver 放在最后-->
55     <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
56     <property name="order" value="1"></property>
57         <property name="mediaTypes">
58             <map>
59                 <!-- 告诉视图解析器，返回的类型为json格式 -->
60                 <entry key="json" value="application/json" />
61                 <entry key="xml" value="application/xml" />

64         </property>
65         <property name="defaultViews">

72     </bean>
73     
74    <!-- 定义跳转的文件的前后缀 ，视图模式配置-->  
75     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
76         <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->  
77         <property name="prefix" value="/WEB-INF/view/" />  
78         <property name="suffix" value=".jsp" />  
79     </bean>  
80 </beans>

5、配置好web.xml就可以测试刚刚配置的Spring+SpringMVC有没有成功。等会儿，全部配置完，记得把注释给取消掉。

 1 <?xml version="1.0" encoding="UTF-8"?>  
 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
 3     xmlns="http://java.sun.com/xml/ns/javaee"  
 4     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"  
 5     version="3.0">  
 6     <display-name>Archetype Created Web Application</display-name>  
 7     <!-- Spring和mybatis的配置文件 -->  
 8 <!--     <context-param>  
 9         <param-name>contextConfigLocation</param-name>  
10         <param-value>classpath:spring-mybatis.xml</param-value>  
11     </context-param>    -->
12     <!-- 编码过滤器 -->  
13     <filter>  
14         <filter-name>encodingFilter</filter-name>  
15         <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  
16         <async-supported>true</async-supported>  
17         <init-param>  
18             <param-name>encoding</param-name>  
19             <param-value>UTF-8</param-value>  
20         </init-param>  
21     </filter>  
22     <filter-mapping>  
23         <filter-name>encodingFilter</filter-name>  
24         <url-pattern>/*</url-pattern>  
25     </filter-mapping>  
26     <!-- Spring监听器 -->  
27 <!--      <listener>  
28         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
29     </listener>   --> 
30     <!-- 防止Spring内存溢出监听器 -->  
31 <!--      <listener>  
32         <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>  
33     </listener>   -->
34   
35     <!-- Spring MVC servlet -->  
36     <servlet>  
37         <servlet-name>SpringMVC</servlet-name>  
38         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
39         <init-param>  
40             <param-name>contextConfigLocation</param-name>  
41             <param-value>classpath:spring-mvc.xml</param-value>  
42         </init-param>  
43         <load-on-startup>1</load-on-startup>  
44         <async-supported>true</async-supported>  
45     </servlet>  
46     <servlet-mapping>  
47         <servlet-name>SpringMVC</servlet-name>  
48         <!-- 此处可以可以配置成*.do，对应struts的后缀习惯 -->  
49         <url-pattern>/</url-pattern>  
50     </servlet-mapping>  
51     <welcome-file-list>  
52         <welcome-file>/index.jsp</welcome-file>  
53     </welcome-file-list>  
54   
55 </web-app>

6、在com.cwj.controller包下创建一个StudentController.java控制器

 1 package com.cwj.controller;
 2 
 3 import org.springframework.stereotype.Controller;
 4 import org.springframework.web.bind.annotation.RequestMapping;
 5 
 6 @Controller
 7 public class StudentController {
 8     
 9     @RequestMapping(value="/test")
10     public String test(){
11 
12         return "com/test";
13     }
14 }

7、根据配置的路径，创建相应的test.jsp文件，之后在tomcat中运行。

8、接下来就是配置spring-mybatis.首先创建application.properties 配置数据库连接信息

 1 jdbc.driver=com.mysql.jdbc.Driver
 2 jdbc.url=jdbc\:mysql\://rm-wz92wfb0l40ny7b5jo.mysql.rds.aliyuncs.com\:3306/test
 3 jdbc.username=root
 4 jdbc.password=CHen123456
 5 
 6 #定义初始连接数  
 7 jdbc.initialSize=0
 8 #定义最大连接数  
 9 jdbc.maxActive=20
10 #定义最大空闲  
11 jdbc.maxIdle=20
12 #定义最小空闲  
13 jdbc.minIdle=1
14 #定义最长等待时间  
15 jdbc.maxWait=60000
16 
17 dbcp.initialSize=15
18 dbcp.maxActive=5000
19 dbcp.maxIdle=0
20 dbcp.maxWait=900000
21 dbcp.defaultAutoCommit=true
22 dbcp.removeAbandoned=true
23 dbcp.removeAbandonedTimeout=30
24 dbcp.whenExhaustedAction=1
25 dbcp.validationQuery=select 1
26 dbcp.testOnBorrow=fasle
27 dbcp.testOnReturn=false

9、配置log4j.properties信息

log4j.rootLogger=INFO,Console,File  
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.Target=System.out  
log4j.appender.Console.layout = org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n  
  
log4j.appender.File = org.apache.log4j.RollingFileAppender  
log4j.appender.File.File = logs/ssm.log  
log4j.appender.File.MaxFileSize = 10MB  
log4j.appender.File.Threshold = ALL  
log4j.appender.File.layout = org.apache.log4j.PatternLayout  
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

10、配置spring-mybatis.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"  
    xsi:schemaLocation="http://www.springframework.org/schema/beans    
                        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd    
                        http://www.springframework.org/schema/context    
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd    
                        http://www.springframework.org/schema/mvc

11、最后测试配置是否成功。

数据库表是这样的

DROP TABLE IF EXISTS `student`;
CREATE TABLE `student` (
  `id` varchar(32) NOT NULL DEFAULT '',
  `name` varchar(255) DEFAULT NULL,
  `age` smallint(6) DEFAULT NULL,
  `sex` smallint(6) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

12、创建实体类Student.java

package com.cwj.pojo;

import javax.persistence.Entity;

@Entity
public class Student {
    private String id;
    private String name;
    private Integer sex;
    private Integer age;
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Integer getSex() {
        return sex;
    }
    public void setSex(Integer sex) {
        this.sex = sex;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
    @Override
    public String toString() {
        return "Student [id=" + id + ", name=" + name + ", sex=" + sex + ", age=" + age + "]";
    }
    
    
}

13、创建StudentDao

package com.cwj.dao;

import java.util.HashMap;
import java.util.Map;

import javax.annotation.Resource;

import org.springframework.jdbc.core.BeanPropertyRowMapper;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.cwj.pojo.Student;

@Repository
public class  StudentDao {
    
    
    
    @Resource
    private NamedParameterJdbcTemplate namedjdbctemp;
    

    @Transactional
    public Student queryStuById(String id){
        String sql = "select * from student where id =:id";
        Map<String, Object> map = new HashMap<String, Object>();
        map.put("id", id);
        return namedjdbctemp.queryForObject(sql, map,new BeanPropertyRowMapper<Student>(Student.class));
    }
    
}

14修改StudentController

package com.cwj.controller;

import javax.servlet.http.HttpServletRequest;

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 com.cwj.dao.StudentDao;
import com.cwj.pojo.Student;

@Controller
public class StudentController {
    
    private static Logger log=LoggerFactory.getLogger(StudentController.class);
    
    @Autowired
    private StudentDao studentService;
    
    @RequestMapping(value="/test")
    public String test(HttpServletRequest request){
        Student student = studentService.queryStuById("2");
        request.setAttribute("stu", student);
        log.info("stu:"+student.toString());
        return "com/test";
    }
}

15、修改test.jsp

 1 package com.cwj.controller;
 2 
 3 import javax.servlet.http.HttpServletRequest;
 4 
 5 import org.slf4j.Logger;
 6 import org.slf4j.LoggerFactory;
 7 import org.springframework.beans.factory.annotation.Autowired;
 8 import org.springframework.stereotype.Controller;
 9 import org.springframework.web.bind.annotation.RequestMapping;
10 
11 import com.cwj.dao.StudentDao;
12 import com.cwj.pojo.Student;
13 
14 @Controller
15 public class StudentController {
16     
17     private static Logger log=LoggerFactory.getLogger(StudentController.class);
18     
19     @Autowired
20     private StudentDao studentService;
21     
22     @RequestMapping(value="/test")
23     public String test(HttpServletRequest request){
24         Student student = studentService.queryStuById("2");
25         request.setAttribute("stu", student);
26         log.info("stu:"+student.toString());
27         return "com/test";
28     }
29 }

16、记得取消web.xml的注释，给张项目结构图便开始测试因为文件夹被我改了名字。所以在github下载的文件访问地址是 http://127.0.0.1:8080/MyBlog/test

静态图片也加载成功。
