SSM整合的配置信息

一、配置pom.xml文件

　　依赖如下：

<!-- 统一管理jar包的版本号 -->

<properties>
        <spring-version>4.3.2.RELEASE</spring-version>
        <spring-aspectj>1.9.2</spring-aspectj>

        <myabtis-spring-version>1.3.2</myabtis-spring-version>
        <mysql-version>5.1.38</mysql-version>
        <c3p0-version>0.9.5.2</c3p0-version>
        <slf4j-log4j-version>1.7.25</slf4j-log4j-version>

        <servlet-version>3.1.0</servlet-version>
        <jstl-version>1.2</jstl-version>
        <jackson-version>2.9.9</jackson-version>
        <junit-version>4.12</junit-version>
        <pagehelper-version>5.1.2</pagehelper-version>
    </properties>

            <artifactId>pagehelper</artifactId>
            <version>${pagehelper-version}</version>
        </dependency>
    </dependencies>
    
    <!-- 添加tomcat插件运行 -->
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <version>2.2</version>
                <configuration>
                    <!-- 设置端口号 -->
                    <port>8080</port>
                    <!-- 设置访问的url，如果是斜线，表示访问路径中不带项目名 -->
                    <path>/</path>
                    <!-- get请求编码格式是utf-8 -->
                    <uriEncoding>UTF-8</uriEncoding>
                </configuration>
            </plugin>
        </plugins>　　<build>

　　当出现java目录下的资源文件无法访问时，在pom.xml中 <build> 标签内的再加上资源文件读取的配置：

<!-- 通过tomcat插件启动项目，需要将mapper.xml也加载进去
            如果配置文件(xml还是properties文件)都放在classpath目录下是不会有问题的,一旦放在src目录下，必须手动定义读取位置
         -->
         <resources>
             <resource>
                 <directory>src/main/java</directory>
                 <includes>
                     <include>**/*.*</include>
                 </includes>
             </resource>
             <resource>
                 <directory>src/main/resources</directory>
                 <includes>
                     <include>**/*.*</include>
                 </includes>
             </resource>
         </resources>

二、配置mybatis的配置文件

<?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>
        <!--打印日志可以看执行的sql语句-->
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    </settings>

    <!-- 配置分页插件 -->
    <plugins>
        <plugin interceptor="com.github.pagehelper.PageInterceptor"></plugin>
    </plugins>

</configuration>

　　其中日志文件的配置如下：

log4j.rootLogger=DEBUG,A1
log4j.logger.org.mybatis=DEBUG
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%c]-[%p] %m%n

三、配置Spring的applicationContext.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:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop"
    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-4.3.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd 
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">
    <!-- 引入数据库属性配置文件 -->
    <context:property-placeholder location="classpath:jdbc.properties"/>
    <!-- 配置连接池 -->
    <bean id="myDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driverClass}"></property>
        <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
        <property name="user" value="${jdbc.user}"></property>
        <property name="password" value="${jdbc.password}"></property>
    </bean>
    
    <!-- 创建SqlSessionFactory，交给spring管理 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 注入数据源 -->
        <property name="dataSource" ref="myDataSource"></property>
        <!-- 加载mybatis的核心配置文件 -->
        <property name="configLocation" value="classpath:mybatis-config.xml"></property>
    </bean>
    <!-- mapper接口通过自动扫描的方式交给spring管理 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 扫描的包地址 -->
        <property name="basePackage" value="cn.kgc.mapper"></property>
        <!-- 注入sqlSeessionFactory -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
    </bean>
    
    <!-- 配置spring的事务管理 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!-- 注入数据源 -->
        <property name="dataSource" ref="myDataSource"></property>
    </bean>
    
    <!-- 定义传播行为/事务的策略 -->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="save*"/>
            <tx:method name="update*"/>
            <tx:method name="delete*"/>
            <tx:method name="find*" read-only="true"/>
            <tx:method name="get*" read-only="true"/>
            <tx:method name="select*" read-only="true"/>
        </tx:attributes>
    </tx:advice>
    
    <!-- 定义切面 -->
    <aop:config>
        <!-- 切入点 -->
        <aop:pointcut expression="execution(* cn.kgc.service.impl.*.*(..))" id="myPointcut"/>
        <!-- 切面 -->
        <aop:advisor advice-ref="txAdvice" pointcut-ref="myPointcut"/>
    </aop:config>
</beans>

　　在使用context方式引用数据库配置文件时，配置文件最好使用多层命名，否则容易与内部命令重名导致无法读取：

my.driver=com.mysql.cj.jdbc.Driver
my.url=jdbc:mysql://localhost:3306/XXX?serverTimezone=UTC&useSSL=false
my.username=root
my.password=root

四、配置SpringMVC的配置文件

<?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:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
        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-4.3.xsd">
    <!-- 开启注解 -->
    <mvc:annotation-driven>
        <mvc:message-converters>
            <ref bean="stringHttpMessageConverter"/>
            <ref bean="mappingJackson2HttpMessageConverter"/>
        </mvc:message-converters>
    </mvc:annotation-driven>
    <!-- 配置扫描器 -->
    <context:component-scan base-package="org.kgc"></context:component-scan>
    
    <!-- 当接受到的请求没有对应的@RequestMapping时,交由Tomcat默认的servlet处理,一般用于访问静态资源 -->
    <mvc:default-servlet-handler/>
    
    <!-- 配置数据格式化 注解 所依赖的bean,在该bean中也可以用来配置类型转换器 -->
    <bean id="formattingConversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean"></bean>
    
    <!-- 配置视图解析器 前缀为/views/ 后缀为.jsp 该解析器渲染成jsp页面 如果是包含jstl的视图会自动转换为对应的JstlView -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/views/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
    <!-- 解决浏览器使用json文件的转换异常问题 -->
    <bean id="mappingJackson2HttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>text/html;charset=UTF-8</value>
            </list>
        </property>
    </bean>
    
    <bean id="stringHttpMessageConverter" class="org.springframework.http.converter.StringHttpMessageConverter"></bean>

</beans>

五、配置web.xml

<?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>MavenWeb</display-name>
  <welcome-file-list>
    <welcome-file>index</welcome-file>
  </welcome-file-list>
  <!-- needed for ContextLoaderListener -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    
    <!-- The front controller of this Spring Web application, responsible for handling all application requests -->
    <servlet>
        <servlet-name>springDispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springMvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <!-- Map all requests to the DispatcherServlet for handling -->
    <servlet-mapping>
        <servlet-name>springDispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <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>
    
    <!-- Spring自带了一个过滤器HiddenHttpMethodFilter，支持GET、POST、PUT、DELETE请求 -->
    <filter>
        <filter-name>HiddenHttpMethod</filter-name>
        <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
    </filter>  
    <filter-mapping>
        <filter-name>HiddenHttpMethod</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

　　至此，ssm所需的配置基本完成。
