首先�Q�spring相关依赖如下�Q?br />

1 <properties>
2   <project.build.sourceEncoding>UTF-8project.build.sourceEncoding>
3     <spring.version>4.1.0.RELEASEspring.version>
4 properties>
5
6 <dependency>
7     <groupId>org.springframeworkgroupId>
8     <artifactId>spring-webmvcartifactId>
9   <version>${spring.version}version>
10 dependency>
11 <dependency>
12     <groupId>org.springframeworkgroupId>
13     <artifactId>spring-webartifactId>
14   <version>${spring.version}version>
15 dependency>

使用springMVC创徏一个可以返回JSON的方法，需要如下书写，关键要�ؓ(f��)特定的方法添�?strong style="color: #ff0000; font-size: 13px; background-color: #eeeeee;">@ResponseBody�Q�将�q�回��D��动�{换�ؓ(f��)JSON格式�Q�作为相应的内容

1     @RequestMapping("/subCates")
2     public @ResponseBody List listSubCates(@Param Integer pId){
3         List cs = categoryService.listCategoryByPcid(pId);
4         return cs;
5     }

该注解需要在xxx-servlet.xml配置中开�?br />

1 <mvc:annotation-driven />

单是如此�q�不够，�l�过调查�Q�springMVC�q�依赖了处理JSON的类库Jackson

1
2 <dependency>
3     <groupId>com.fasterxml.jackson.coregroupId>
4     <artifactId>jackson-coreartifactId>
5     <version>2.5.0version>

16      <artifactId>jackson-mapper-aslartifactId>
17      <version>1.9.13version>
18 dependency>

本�h最开始只依赖了mapper和core�Q�没有添加databind依赖才导致了406错误。调查之后发玎ͼ�其实只需要添加databind依赖��可以解决问题，databind依赖了core�{�配�|��?img src ="http://www.tkk7.com/produ/aggbug/422480.html" width = "1" height = "1" />
