使用SpsringMVC，使用restEasy调试，controller请求设置如下： Java代码 @RequestMapping(value="/list",method=RequestMethod.GET,produces=MediaType.APPLICATION_JSON_VALUE) @ResponseBody public List<EditTimeout> list(){ List<EditTimeout> list = editImpl.selectAll(); return list; } 请求，debug跟踪list是返回值没有问题，但是前台页面报如下错误： Java代码 Response Status: 406 (Not Acceptable) Response RAW返回值如下，（前半部分） Xml代码 HTTP GET http://127.0.0.1:8080/onlineLibrary/rest/system/editTimeout/list Host: 127.0.0.1:8080 406 Not Acceptable Date: Sat, 17 Aug 2013 11:01:07 GMT Server: Apache-Coyote/1.1 Content-Length: 1067 Content-Type: text/html;charset=utf-8 <html><head><title>Apache Tomcat/7.0.34 - Error report</title><style> 后台提示错误： Java代码 2013-08-17 19:01:03,116 DEBUG org.springframework.web.servlet.DispatcherServlet -Last-Modified value for [/onlineLibrary/rest/system/editTimeout/list] is: -1 2013-08-17 19:01:07,606 DEBUG org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver -Resolving exception from handler [public java.util.List<com.online.ol.filter.EditTimeout> com.online.ol.filter.EditTimeoutContoller.list()]: org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representation 2013-08-17 19:01:07,680 DEBUG org.springframework.web.servlet.mvc.annotation.ResponseStatusExceptionResolver -Resolving exception from handler [public java.util.List<com.online.ol.filter.EditTimeout> com.online.ol.filter.EditTimeoutContoller.list()]: org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representation 2013-08-17 19:01:07,681 DEBUG org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver -Resolving exception from handler [public java.util.List<com.online.ol.filter.EditTimeout> com.online.ol.filter.EditTimeoutContoller.list()]: org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representation 引起的原因： 由于设置了@ResponseBody,要把对象转换成json格式，缺少转换依赖的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。 jackson-mapper-asl-1.9.12.jar (762.1 KB)下载次数: 594 jackson-core-asl-1.9.12.jar (226.8 KB)下载次数: 475转载于:https://www.cnblogs.com/cuizhf/p/4261548.html
