SpringMVC+Spring+Mybatis整合配置 / 憋错料

1、Maven依赖文件：pom.xml

  </dependencies>
  <build>
    <finalName>ssm</finalName>

</project>

2、web.xml

web.xml规定了有哪些显式的servlet，规定了最顶层的Context环境，是整个的纲领。它同时规定了对于哪些URL的请求归哪些servlet处理，哪些URL使用哪种编码方式。需要注意的是，对于没有人为指定配置文件的servlet，会自动在WEB-INF文件夹下找servletName-servlet.xml的文件作为其配置。

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"  xmlns="http://java.sun.com/xml/ns/javaee"
	     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

  <display-name>SSM Web Application</display-name>

  <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:applicationContext.xml</param-value>
        <!--指定Context的配置文件-->
  </context-param>

  <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>

            <param-value>true</param-value>
        </init-param>
    </filter>

    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <servlet>
        <servlet-name>ssm</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:config/webmvc-config.xml</param-value>
		</init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>ssm</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

3、springMVC配置：webmvc-config.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:p="http://www.springframework.org/schema/p" 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-4.0.xsd
	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
	http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

	<!--处理对静态资源的访问-->
	<mvc:resources location="/common/"   mapping="/common/**"/>
	<mvc:resources location="/images/"   mapping="/images/**" />
	<mvc:resources location="/js/"       mapping="/js/**" />
	<mvc:resources location="/css/"      mapping="/css/**" />
	<mvc:resources location="/styles/"   mapping="/styles/**" />
	<mvc:resources location="/htm/"      mapping="/htm/**" />

        <import resource="view-controller.xml" />

        <context:annotation-config/>

	<context:component-scan base-package="com.zmx.ssm" use-default-filters="false">
		 <context:include-filter expression="org.springframework.stereotype.Controller" type="annotation" />
	</context:component-scan>

    <!--规定模板文件的类型和位置-->
    <bean id="velocityConfigurer"
        class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
        <property name="resourceLoaderPath" value="templates/" />
        <property name="velocityProperties">
            <props>
                <prop key="input.encoding">utf-8</prop>
                <prop key="output.encoding">utf-8</prop>
            </props>
        </property>
    </bean>
    <!--配置附加工具，以及将后缀为vm的文件交给下面的Resolver处理-->
    <bean id="velocityViewResolver"
        class="org.springframework.web.servlet.view.velocity.VelocityViewResolver">
        <property name="suffix" value=".vm" />
        <property name="contentType" value="text/html;charset=utf-8" />
        <property name="toolboxConfigLocation" value="/WEB-INF/toolbox.xml"/>
    </bean>

</beans>

4、applicationContext.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:jee="http://www.springframework.org/schema/jee"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
	                    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
	                    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
	                    http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.0.xsd
	                    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">
    <!-- 引入属性文件 -->
    <context:property-placeholder location="classpath*:/application.properties" />

    <context:spring-configured /> 

    <!-- 注解bean及依赖注入 -->
	<context:component-scan base-package="com.zmx.ssm">
		<context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation" />
	</context:component-scan>

    <!--数源设置-->
    <bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource"
        destroy-method="close">
        <property name="driverClassName" value="${db.driverClass}" />
        <property name="url" value="${db.url}" />
        <property name="username" value="${db.username}" />
        <property name="password" value="${db.password}" />
    </bean>

    <!--sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <!--规定了扫描mapper文件的路径-->
        <property name="mapperLocations" value="classpath*:mapper/*.xml" />
        <!--指定了Mybatis配置文件的路径-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

    <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
        <constructor-arg index="0" ref="sqlSessionFactory" />
    </bean>

    <!--这一段让我们的MapperInterface能够最终在Spring中生成Bean最后被AutoWired-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.zmx.ssm.**.mapper" />
    </bean>

    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!-- 开启注解事务 -->
    <tx:annotation-driven transaction-manager="transactionManager"/>
</beans>

5、Mybatis配置:mybatis-config.xml

<?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>
    <typeAliases>
        <!--POJO 类的所在package，默认类名为其Alias-->
        <package name="com.zmx.ssm.user.domain"/>
    </typeAliases>
    <mappers>
        <!--映射文件所在的地方-->
        <mapper resource="UserMapper.xml" />
    </mappers>
</configuration>

6、velocity模板引擎：toolbox.xml

<?xml version="1.0" encoding="UTF-8"?>
<toolbox>
    <tool>
        <key>date</key>
        <scope>request</scope>
        <class>
            org.apache.velocity.tools.generic.DateTool
        </class>
        <parameter name="format" value="yyyy-MM-dd HH:mm:ss"/>
    </tool>
    <tool>
        <key>link</key>
        <scope>request</scope>
        <class>org.apache.velocity.tools.view.tools.LinkTool</class>
    </tool>
    <tool>
        <key>stringUtils</key>
        <scope>request</scope>
        <class>org.apache.velocity.util.StringUtils</class>
    </tool>
    <tool>
        <key>math</key>
        <scope>application</scope>
        <class>org.apache.velocity.tools.generic.MathTool</class>
    </tool>
    <tool>
        <key>esc</key>
        <scope>request</scope>
        <class>org.apache.velocity.tools.generic.EscapeTool</class>
    </tool>
    <tool>
        <key>params</key>
        <scope>request</scope>
        <class>org.apache.velocity.tools.view.tools.ParameterParser</class>
    </tool>
</toolbox>

7、Mybatis映射文件

8、使用Spring-test测试

package test.com.zmx.ssm.user;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.transaction.TransactionConfiguration;
import org.springframework.transaction.annotation.Transactional;

import com.zmx.ssm.user.domain.User;
import com.zmx.ssm.user.mapper.UserMapper;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:applicationContext.xml"})
@TransactionConfiguration(transactionManager="transactionManager",defaultRollback=false)
@Transactional
public class UserDaoTest {

    @Autowired
    private UserMapper userMapper;

    @Test
    public void testInsert() {
        User user=new User();
        user.setAccount("manager");
        user.setPassword("123456");
        userMapper.addUser(user);
    }

}

9、小结

Spring常用的注解主要有以下几种：

@Component
@Service--业务层
@Respority--持久化层
@Controller--视图层

尽管这几种注解对应的意义不一样，但它们都有一个共同的作用，那就是让Spring找到并且最终生成对应的Bean。举个例子，我们在Service中使用接口UserDAO，但该接口的实例我们并没有指定使用哪一个，虽然我们写了对应的Impl Class。通过注解生成Bean，Spring就能够在Service调用该接口的时候从容器里得到正确的实体对象。
