spring4.3+mybatis3.4+freemark+log4j2+fastjson整合

2017-7-1 更新 spring 版本 4.3.9  更新mybatis 为3.4.3

0、先写下文件结构防止配置放错地方

1、首先发下maven配置

<properties>

        <java.version>1.8</java.version>
        <!--依赖版本-->

                </configuration>
            </plugin>
        </plugins>
    </build>

简单说明以下包的作用：

spring-web 是对servlet的封装 核心包

spring-webmvc 是在spring-web的基础上添加mvc支持 例如v层适配,这里freemark模板引擎就用到了其中的 org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver类

spring-context-support 是对常用bean的扩展 其中 FreeMarkerConfigurer会依赖此包的 org.springframework.ui.freemarker.FreeMarkerConfigurationFactory

javax.servlet-api 是核心api这里使用3.1

spring-aspects 提供对AspectJ的支持

spring-tx 对事物支持 @Transactional 就在此包中

spring-jdbc 对jdbc的封装,方便spring管理jdbc 该项目中事物的管理便是使用了 org.springframework.jdbc.datasource.DataSourceTransactionManager

fastjson 这个包是用来处理返回json数据问题 来自阿里值得信赖

2、然后是 web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
         http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">

    <!-- 区分项目名称，防止默认重名 -->
    <context-param>
        <param-name>webAppRootKey</param-name>
        <param-value>maven.xxl_web.root</param-value>
    </context-param>

    <!-- 字符集 过滤器  -->
    <filter>
        <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- 设置Spring容器加载配置文件路径 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext-*.xml</param-value>
    </context-param>

    <!-- Spring view分发器 -->
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
        <!--拦截/*，这是一个错误的方式，请求可以走到Action中，但转到jsp时再次被拦截，不能访问到jsp。
            拦截/，restful风格 弊端：会导致静态文件（jpg,js,css）被拦截后不能正常显示。解决办法看dispatcher-->
    </servlet-mapping>

    <!-- Spring会创建一个WebApplicationContext上下文，称为父上下文（父容器） ，保存在 ServletContext中，key是WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE的值。
    可以使用Spring提供的工具类取出上下文对象：WebApplicationContextUtils.getWebApplicationContext(ServletContext);

    DispatcherServlet是一个Servlet,可以同时配置多个，每个 DispatcherServlet有一个自己的上下文对象（WebApplicationContext），称为子上下文（子容器），子上下文可以访问父上下文中的内容，
    但父上下文不能访问子上下文中的内容。 它也保存在 ServletContext中，key是"org.springframework.web.servlet.FrameworkServlet.CONTEXT"+Servlet名称。当一个Request对象产生时，
    会把这个子上下文对象（WebApplicationContext）保存在Request对象中，key是DispatcherServlet.class.getName() + ".CONTEXT"。
    可以使用工具类取出上下文对象：RequestContextUtils.getWebApplicationContext(request);-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>


       <!-- log4j2-begin --> <!-- 注意！ 由于使用3.1版本web.xml log4j2 会自动注册 如果使用2.5版本xml 需要手动注册 以下代码-->
    <!--<listener>-->
        <!--<listener-class>org.apache.logging.log4j.web.Log4jServletContextListener</listener-class>-->
    <!--</listener>-->

    <!--<filter>-->
        <!--<filter-name>log4jServletFilter</filter-name>-->
        <!--<filter-class>org.apache.logging.log4j.web.Log4jServletFilter</filter-class>-->
    <!--</filter>-->
    <!--<filter-mapping>-->
        <!--<filter-name>log4jServletFilter</filter-name>-->
        <!--<url-pattern>/*</url-pattern>-->
        <!--<dispatcher>REQUEST</dispatcher>-->
        <!--<dispatcher>FORWARD</dispatcher>-->
        <!--<dispatcher>INCLUDE</dispatcher>-->
        <!--<dispatcher>ERROR</dispatcher>-->
    <!--</filter-mapping>-->
    <!-- log4j2-end -->

</web-app>

ps:没什么说的 使用restfull风格 因为这样可以灵活控制以什么结尾

3、下面是dispatcher的spring配置(这个配置是view层相关的,配置了freemark模板引擎和静态文件)

4、下面发下applicationContext-bean.xml的配置

        <property name="configLocation" value="classpath:mybatis.xml"/>
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
    </bean>

    <!-- 配置mybatis dao注册，所有dao都继承sqlMapper
    annotationClass：当指定了annotationClass的时候，MapperScannerConfigurer将只注册使用了annotationClass注解标记的接口。
    markerInterface：markerInterface是用于指定一个接口的，当指定了markerInterface之后，MapperScannerConfigurer将只注册继承自markerInterface的接口。
          如果上述两个属性都指定了的话，那么MapperScannerConfigurer将取它们的并集，而不是交集。即使用了annotationClass进行标记或者继承自markerInterface
          的接口都将被注册为一个MapperFactoryBean。
          除了用于缩小注册Mapper接口范围的属性之外，我们还可以指定一些其他属性，如：
    sqlSessionFactory：这个属性已经废弃。当我们使用了多个数据源的时候我们就需要通过sqlSessionFactory来指定在注册MapperFactoryBean的时候需要使用的SqlSessionFactory，
        因为在没有指定sqlSessionFactory的时候，会以Autowired的方式自动注入一个。换言之当我们只使用一个数据源的时候，即只定义了一个SqlSessionFactory的时候我们就可以不给
        MapperScannerConfigurer指定SqlSessionFactory。
    sqlSessionFactoryBeanName：它的功能跟sqlSessionFactory是一样的，只是它指定的是定义好的SqlSessionFactory对应的bean名称。
    sqlSessionTemplate：这个属性已经废弃。它的功能也是相当于sqlSessionFactory的，因为就像前面说的那样，MapperFactoryBean最终还是使用的SqlSession的getMapper
    方法取的对应的Mapper对象。当定义有多个SqlSessionTemplate的时候才需要指定它。对于一个MapperFactoryBean来说SqlSessionFactory和SqlSessionTemplate只需要其中一个就可以了，
    当两者都指定了的时候，SqlSessionFactory会被忽略。
    sqlSessionTemplateBeanName：指定需要使用的sqlSessionTemplate对应的bean名称。-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.test.app.dao"/>
    </bean>


</beans>

5、ini.properties就不发了

6、generatorConfig.xml配置（）

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE generatorConfiguration PUBLIC
        "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" >
<generatorConfiguration>

    <!-- !!!! Driver Class Path !!!! -->
    <classPathEntry location="E:.m2

    <context id="context" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressAllComments" value="true"/>
            <property name="suppressDate" value="true"/>
        </commentGenerator>

        <!-- !!!! Database Configurations !!!! -->
        <jdbcConnection driverClass="${datasource.driver}"
                        connectionURL="${datasource.url}"
                        userId="${datasource.username}"
                        password="${datasource.password}"/>

        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>

        <!-- !!!! Model Configurations !!!! -->
        <javaModelGenerator targetPackage="com.hmc.crm.entity" targetProject="srcmainjava">

            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!-- !!!! Mapper XML Configurations !!!! -->
        <sqlMapGenerator targetPackage="com.hmc.crm.dao" targetProject="srcmainjavamapper">
            <property name="enableSubPackages" value="false"/>
        </sqlMapGenerator>

        <!-- !!!! Mapper Interface Configurations !!!! -->
        <javaClientGenerator targetPackage="com.hmc.crm.dao" targetProject="srcmainjava" type="XMLMAPPER">

        <!-- !!!! Table Configurations !!!! -->
        <table tableName="UserType" enableCountByExample="false" enableDeleteByExample="false" enableSelectByExample="false"
               enableUpdateByExample="false"/>
    </context>
</generatorConfiguration>

ps:在pom中配置过mybatis的generator插件 会自动读取 resources下的generatorConfig.xml 只需要双击插件即可如下图：

 7、mybatis.xml配置

<?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>
        <!-- Globally enables or disables any caches configured in any mapper under this configuration -->
        <setting name="cacheEnabled" value="false"/>
        <!-- Sets the number of seconds the driver will wait for a response from the database -->
        <setting name="defaultStatementTimeout" value="3000"/>
        <!-- Enables automatic mapping from classic database column names A_COLUMN to camel case classic Java property names aColumn -->
        <setting name="mapUnderscoreToCamelCase" value="true"/>
        <!-- Allows JDBC support for generated keys. A compatible driver is required.
        This setting forces generated keys to be used if set to true,
         as some drivers deny compatibility but still work -->
        <setting name="useGeneratedKeys" value="true"/>
        <setting name="logImpl" value="LOG4J2"/>
    </settings>

    <!-- Continue going here -->

</configuration>

8、log4j2.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="off" monitorInterval="1800">

    <properties>
        <property name="LOG_HOME">/logs/sample</property>
        <property name="FILE_NAME">mylog</property>
    </properties>

    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
        </Console>

        <RollingRandomAccessFile name="running-log"
                                 fileName="${LOG_HOME}/${FILE_NAME}.log"
                                 filePattern="${LOG_HOME}/$${date:yyyy-MM}/${FILE_NAME}-%d{yyyy-MM-dd}-%i.log.gz">
            <PatternLayout
                    pattern="%date{yyyy-MM-dd HH:mm:ss.SSS} %level [%thread][%file:%line] - %msg%n"/>
            <Policies>
                <TimeBasedTriggeringPolicy/>
                <SizeBasedTriggeringPolicy size="10 MB"/>
            </Policies>
            <DefaultRolloverStrategy max="20"/>
        </RollingRandomAccessFile>
    </Appenders>

    <Loggers>
        <!--<Logger name="com.test.app" level="trace" additivity="true">-->
            <!--<AppenderRef ref="running-log"/>-->
        <!--</Logger>-->
        <Logger name="com.test.app.dao" level="DEBUG" additivity="true">
            <AppenderRef ref="Console"/>
        </Logger>
        <Root level="error">
            <AppenderRef ref="Console"/>
        </Root>
    </Loggers>
</Configuration>

ps: 在mybatis.xml中红色部分配置了日志实现方式。在log4j2中配置了dao层日志 为DEBUG且为 console 方式 方便调试时查看sql

接下来就是代码部分：

1、将generator生成的XXXXMapper.java拷贝到dao层下

2、新建HelloService.java和HelloServiceImpl.java 在service层下

public interface HelloService {
    public List<testModel> getAll();

}

@Service
public class HelloServiceImpl implements HelloService {

    @Autowired
    private XXXMapper dao;

    public List<testModel> getAllLabels() { return dao.selectAll(); } 
}

3、新建HelloController.java 在controller层下

@Controller
@RequestMapping("/hello")
public class HelloController {

    @Autowired
    private HelloService service;

    @RequestMapping("/index.html")
    public String index(Model model) {
        model.addAttribute("title", "hello spring mvc");
        model.addAttribute("model","正常显示");
        return "index";
    }

    @RequestMapping("/list.html")
    public String test(Model model, @RequestParam(defaultValue = "") String key) {
        List<testModel> ans=service.getAll();
        model.addAttribute("all", ans);
        return "list";
    }

    @RequestMapping("/list")
    @ResponseBody
    public List<testModel> list(){
        List<testModel> ans=service.getAll(); return ans; } 
}

4、在webapp/WEB-INF/view下新建list.ftl

<!DOCTYPE html>
<html lang="zh">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<table border="1">
    <tr>
        <th>名字</th>
        <th>年龄</th>
    </tr>
<#list all as label>
    <tr>
        <td>${label.name}</td>
        <td>${label.age}</td>
    </tr>
</#list>
</table>

</body>
</html>

5.运行尝试

 

2017-7-16号更新  还是用spring boot 吧反正都帮你配好了 为什么不用呢  而且还可以打包成war 手动doge
