原因是
1、配置文件中路径的问题，读dispatchServlet时将jsp文件一起读入核心控制器，原来是：
1 <servlet> 2 <servlet-name>dispatcherServlet</servlet-name> 3 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 4 <init-param> 5 <param-name>contextConfigLocation</param-name> 6 <param-value>classpath:spring.xml</param-value> 7 </init-param> 8 </servlet> 9 <servlet-mapping> 10 <servlet-name>dispatcherServlet</servlet-name> 11 <url-pattern>/*</url-pattern> 12 </servlet-mapping>
修改为
1 <servlet> 2 <servlet-name>dispatcherServlet</servlet-name> 3 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 4 <init-param> 5 <param-name>contextConfigLocation</param-name> 6 <param-value>classpath:spring.xml</param-value> 7 </init-param> 8 </servlet> 9 <servlet-mapping> 10 <servlet-name>dispatcherServlet</servlet-name> 11 <url-pattern>*.do</url-pattern> 12 </servlet-mapping>
2、RESTful约束下，requestMapping注解使用有效，getMapping注解无效
查找得知为没有设置json的支持包，
Java下常见的Json类库有Gson、JSON-lib和Jackson等，Jackson相对来说比较高效，在项目中主要使用Jackson进行JSON和Java对象转换。
在pom.xml文件中配置依赖：
1 <dependency> 2 <groupId>com.fasterxml.jackson.core</groupId> 3 <artifactId>jackson-databind</artifactId> 4 <version>2.8.3</version> 5 </dependency>
再次启动Tomcat成功
