最后发现 同一个类中映射了两个相同的路径

下面还有一个方法用了相同的params  
@RequestMapping(params = "getProduct")  
public void meth··()\{  
    ·······  
\}

————————————————————  
@RequestMapping("/testRequestMap")  
@ResponseBody  
public String testRequestMap1()\{  
    return "testRequestMap1";  
\}

@RequestMapping("testRequestMap")  
@ResponseBody  
public String testRequestMap2()\{  
    return "testRequestMap2";  
\}

加不加 /  貌似没区别  官网都加/
