SpringMVC返回JSON对象遇到的错误

SPringMVC返回JSON对象遇到报错：org.springframework.web.servlet.handler.AbstractHandlerExceptionResolver.logException Resolved [org.springframework.http.converter.HttpMessageNotWritableException: No converter for [class java.util.ArrayList] with preset Content-Type 'null']

错误代码

  @RequestMapping(value = "/test" , produces = {"text/html" , "application/json"})

改正后

  @RequestMapping(value = "/test" , produces = {MediaType.APPLICATION_JSON_VALUE})

错误原因

SpringMVC在解析返回对象的时候produces属性的text/html和application/json有冲突
