SpringMVC报错

报错为：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping': Invocation of init method failed; nested exception is java.lang.IllegalStateException: Ambiguous mapping. Cannot map 'spittleController' method 
public java.lang.String com.cui.action.SpittleController.spittleList()
to {[],methods=[GET]}: There is already 'mainController' bean method
public java.lang.String com.cui.action.MainController.index() mapped.

经过试验后发现是使用@RequestMapping注解时，使用了两个name属性，查源码可知：

    String name() default "";

    @AliasFor("path")
    String[] value() default {};

    @AliasFor("value")
    String[] path() default {};

    RequestMethod[] method() default {};

    String[] params() default {};

    String[] headers() default {};

    String[] consumes() default {};

    String[] produces() default {};

其他属性是数组，可定义多了，name属性是String，只能定义一个。问题找到了，我在代码中用了多个name属性~

解决方法：把name改成value~
