@ResponseBody

在开发接口时发现了一个很好玩的问题，两个接口均是restful形式，参数在URL路径中传递，返回结果形式均为json，但是在接口测试时，一个接口正常，另一个接口报错：The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers.本文来分析一下其中的原因。   先介绍一下出错的接口情况，接口代码如下： /** * 验证email是否可用 * @param email * @return */ @ResponseBody @RequestMapping(value = "/emailCheck/{email}", method = RequestMethod.GET) @ApiOperation(value = "验证email是否可用", httpMethod = "GET", response = ApiResult.class, notes = "验证email是否可用") public ApiResult checkEmailValid(@ApiParam(required = true, name = "email",

搭建 SpringMVC(4.1) ，但是搭建完成以后发现使用 @ResponseBody的ajax无法访问，总是出现406的问题。 首先怀疑的是配置问题，经过查明，影响SpringMVC的 @ResponseBody注解的是： <mvc:annotation-driven />，我发现我的配置中存在这个注解。同时又使用Spring文档中的自动配置相关解析类的方式再进行测试，发现还是没有解决问题。 同时在网上找到相关问题，发现是 缺失jackson的jar 。 <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-core-lgpl</artifactId> <version>1.9.0</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-lgpl</artifactId> <version>1.9.0</version> </dependency> 于是加上该依赖，可是发现问题还是没有解决。 有参考一下spring 文档 Spring 4 requires the recent Hibernate Validator 4.3+, and

Spring reference写到： Mapping the response body with the @ResponseBody annotation The @ResponseBodyannotation is similar to @RequestBody. This annotation can be put on a method and indicates that the return type should be written straight to the HTTP response body (and not placed in a Model, or interpreted as a view name). For example: @RequestMapping(value = "/something", method = RequestMethod.PUT) @ResponseBody public String helloWorld() { return "Hello World"; } The above example will result in the text Hello World being written to the HTTP response stream. As with @RequestBody, Spring
