基于spring的应用，主页可访问，无法访问URL对应的应用资源

先给出解决方式：

<mvc:annotation-driven/>一定要在前，<context:component-scanbase-package="com.controller.*"/>在后，否则浏览器无法通过URL访问到应用中具体的类及方法。

把junit的maven引用去掉，去掉如下依赖，maven——》update project

<dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>3.8.1</version>      <scope>test</scope>    </dependency>

maven配置文件如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>wsapcloud</groupId>  <artifactId>wsapcloud</artifactId>  <version>0.0.1-SNAPSHOT</version>  <packaging>war</packaging>        <dependencies>  <dependency>  <groupId>dom4j</groupId>  <artifactId>dom4j</artifactId>  <version>1.6.1</version>  </dependency>  <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-context</artifactId>        <version>4.3.0.RELEASE</version>    </dependency>    <!--     <dependency>        <groupId>org.springframework.ws</groupId>        <artifactId>spring-ws-core</artifactId>        <version>2.3.0.RELEASE</version>    </dependency>     -->          <dependency>         <groupId>org.springframework</groupId>         <artifactId>spring-webmvc</artifactId>         <version>4.3.0.RELEASE</version>     </dependency>     <!--       <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-web</artifactId>            <version>4.3.0.RELEASE</version>    </dependency>     --><dependency>   <groupId>log4j</groupId>   <artifactId>log4j</artifactId>   <version>1.2.17</version></dependency>  <dependency>    <groupId>org.apache.logging.log4j</groupId>    <artifactId>log4j-api</artifactId>    <version>2.6.1</version>  </dependency>  <dependency>    <groupId>org.apache.logging.log4j</groupId>    <artifactId>log4j-core</artifactId>    <version>2.6.1</version>  </dependency>    <dependency>    <groupId>org.apache.logging.log4j</groupId>    <artifactId>log4j-web</artifactId>    <version>2.6.1</version>  </dependency> <dependency>    <groupId>com.fasterxml.jackson.core</groupId>    <artifactId>jackson-core</artifactId>    <version>2.7.5</version></dependency><dependency>    <groupId>com.fasterxml.jackson.core</groupId>    <artifactId>jackson-databind</artifactId>    <version>2.7.5</version></dependency><dependency>    <groupId>org.codehaus.jackson</groupId>    <artifactId>jackson-core-asl</artifactId>    <version>1.9.13</version></dependency><dependency>    <groupId>com.fasterxml.jackson.core</groupId>    <artifactId>jackson-annotations</artifactId>    <version>2.7.5</version></dependency><dependency>    <groupId>org.codehaus.jackson</groupId>    <artifactId>jackson-mapper-asl</artifactId>    <version>1.9.13</version></dependency><dependency>    <groupId>org.json</groupId>    <artifactId>json</artifactId>    <version>20160212</version></dependency><!--  <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>3.8.1</version>      <scope>test</scope>    </dependency> -->     </dependencies>  <dependencyManagement>  <dependencies>    <dependency>      <groupId>org.apache.logging.log4j</groupId>      <artifactId>log4j-bom</artifactId>      <version>2.6.1</version>      <scope>import</scope>      <type>pom</type>    </dependency>  </dependencies></dependencyManagement>    <build>    <plugins>      <plugin>        <artifactId>maven-war-plugin</artifactId>        <version>2.6</version>        <configuration>          <warSourceDirectory>WebContent</warSourceDirectory>          <failOnMissingWebXml>false</failOnMissingWebXml>        </configuration>      </plugin>      <plugin>        <artifactId>maven-compiler-plugin</artifactId>        <version>3.5</version>        <configuration>          <source>1.7</source>          <target>1.7</target>        </configuration>      </plugin>    </plugins>  </build></project>

基于spirng的应用中，需要在web.xml中增加下面类似的配置信息

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>  <servlet>    <servlet-name>springmvc</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:config/spring/springmvc-servlet.xml</param-value>    </init-param>      <load-on-startup>1</load-on-startup>  </servlet>  <servlet-mapping>    <servlet-name>springmvc</servlet-name>    <url-pattern>/</url-pattern>  </servlet-mapping>  <!--因为使用DispatcherServlet拦截“/”，为了实现rest风格，拦截了所有的请求，那么同时对*.js , *.jpg, *.html等  静态文件的访问也被拦截，因此需要如下处理  -->  <servlet-mapping>    <servlet-name>default</servlet-name>    <url-pattern>*.html</url-pattern>  </servlet-mapping>    <servlet-mapping>    <servlet-name>default</servlet-name>    <url-pattern>*.js</url-pattern>  </servlet-mapping>    <servlet-mapping>    <servlet-name>default</servlet-name>    <url-pattern>*.css</url-pattern>  </servlet-mapping>

springmvc-servlet.xml 包含如下信息

<mvc:annotation-driven/><context:component-scan base-package="com.controller.*" />

需要注意的是，<mvc:annotation-driven/>一定要在前，<context:component-scan base-package="com.controller.*" />

在其后，否则，浏览器客户端URL请求到达前端控制器DispatcherServlet，前端控制器无法将请求映射到指定端点，导致客户端返回404错误
无法访问应用的内部路径
