Question

SpringMVC中使用List数据绑定，ajax怎么传输包含数组的Json数据

Answer 1

用spring mvc3的注解@ResponseBody

@ResponseBody
public List<String> xxxx() {
...
List res = xxx
return res;
}
加两个依赖

<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.8.4</version>
</dependency>

<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-core-asl</artifactId>
<version>1.8.4</version>
</dependency>
如果没配

<mvc:annotation-driven />
还需配置

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />
</list>
</property>
</bean>

Answer 2

json数据本质都是字符串，只是和解析的方式不同，保证你传的字符串能被解析成json数组就Ok了
