spring 版本:3.2.4 html
跟踪到spring mvc中查看到的异常:
org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representation java
spring中抛出异常的方法: web
org.springframework.web.servlet.DispatcherServlet.doDispatch(HttpServletRequest request, HttpServletResponse response) throws Exception spring
@RequestMapping(value="awardByPage",produces="text/plain;charset=UTF-8") public @ResponseBody JSONResponse awardByPage(@RequestParam int pageIndex) { return JSONResponse.buildSuccess(awardService.awardLogByPage(pageIndex)); }
1. 删除代码中的: json
,produces="text/plain;charset=UTF-8"2. 网络上查找的其它解决方案:
<!-- 启动JSON格式的配置 --> <bean id="jacksonMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> <!--解决 HttpMediaTypeNotAcceptableException: Could not find acceptable representation --> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean>
1. controller中返回的内容没有get方法, 网络
解决办法:添加get方法; mvc
2. 因为设置了@ResponseBody,要把对象转换成json格式,缺乏转换依赖的jar包,故此错。
解决办法: 加入依赖的jar,jackson-core-asl-1.9.12.jar,jackson-mapper-asl-1.9.12.jar问题解决。
