HTTP Status 406 - @ResponseBody 返回json报错

缺少jar包

    
          
            com.fasterxml.jackson.core  
            jackson-databind  
            ${jackson.version}  
          
  
      
     

@RequestMapping设置错误 如

@RequestMapping(value = "/xx/xx", produces = "text/html;charset=UTF-8")

@RequestMapping(value = "/xx/xx", produces = "text/plain;charset=UTF-8")

应设置成

@RequestMapping(value = "/xx/xxx", produces = "application/json;charset=UTF-8")
