Maven+SpringMVC+Mybatis项目搭建（二）

SpringMVC配置

1，通过maven，添加springmvc框架的依赖包：

pom.xml文件：

<properties>
     <spring.version>4.3.5.RELEASE</spring.version>
</properties>

<dependencies>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aop</artifactId>
        <version>${spring.version}</version>
    </dependency>
     <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aspects</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-beans</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-expression</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-test</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-tx</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>${spring.version}</version>
    </dependency>
</dependencies>

2，修改web.xml文件，使用SpringMVC拦截请求：

<!-- 监听器 创建上下文监听器 -->  
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 配置初始化参数 -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring-*.xml</param-value>
</context-param>

<servlet>
    <servlet-name>spring-mvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>spring-mvc</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

3，添加spring-mvc.xml文件

包自动扫描： http://blog.youkuaiyun.com/chunqiuwei/article/details/16115135
视图解析：http://elim.iteye.com/blog/1770554

<!-- 自动扫描包，并注入容器 -->
<context:component-scan base-package="com.yang.controller" use-default-filters="false">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<context:component-scan base-package="com.yang.service" use-default-filters="false">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Service"/>
</context:component-scan>
<context:component-scan base-package="com.yang.dao" use-default-filters="false">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Repository"/>
</context:component-scan>

<!-- 试图解析器 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/jsp/"/>
    <property name="suffix" value=".jsp"/>
</bean>

*遇到问题：

1，pom.xml中${spring.version }使用时报错：注意，

    ${spring.version }中‘{}’和里面的单词间应该没有 空格；

2，使用tomcat_v8.5.9时，报错：The Apache Tomcat installation at this directory is version 8.5.9. A Tomcat 8.0 installation is expected.

解决方法：
①在Tomcat的安装目录中找到lib目录，再找到catalina.jar。使用压缩软件（WinRAR或是好压）打开
它。
②依次找到并双击打开org\apache\catalina\util\ServerInfo.properties 文件
    server.info=Apache Tomcat/8.5.6
    server.number=8.5.6.0
    server.built=Oct 6 2016 20:15:31 UTC
改为：
    server.info=Apache Tomcat/8.0.0
    server.number=8.0.0
    server.built=Oct 6 2016 20:15:31 UTC
