1.web.xml里配置
<!--
配置 org.springframework.web.filter.HiddenHttpMethodFilter: 可以把 POST 请求转为 DELETE 或 put 请求
-->
<filter>
<filter-name>HiddenHttpMethodFilter</filter-name>
<filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>HiddenHttpMethodFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
2.控制层代码:
/**
* Rest 风格的 URL. 以 CRUD 为例: 新增: /order POST 修改: /order/1 PUT update?id=1 获取:
* /order/1 GET get?id=1 删除: /order/1 DELETE delete?id=1
*
* 如何发送 PUT 请求和 DELETE 请求呢 ? 1. 需要配置 HiddenHttpMethodFilter 2. 需要发送 POST 请求
* 3. 需要在发送 POST 请求时携带一个 name="_method" 的隐藏域, 值为 DELETE 或 PUT
*
* 在 SpringMVC 的目标方法中如何得到 id 呢? 使用 @PathVariable 注解
*
*/
@RequestMapping(value = "/testRest/{id}", method = RequestMethod.PUT)
public String testRestPut(@PathVariable Integer id) {
System.out.println("testRest Put: " + id);
return SUCCESS;
}
@RequestMapping(value = "/testRest/{id}", method = RequestMethod.DELETE)
public String testRestDelete(@PathVariable Integer id) {
System.out.println("testRest Delete: " + id);
return SUCCESS;
}
3.jsp页面
<form action="springmvc/testRest/1" method="post">
<input type="hidden" name="_method" value="PUT"/>
<input type="submit" value="TestRest PUT"/>
</form>
<br><br>
<form action="springmvc/testRest/1" method="post">
<input type="hidden" name="_method" value="DELETE"/>
<input type="submit" value="TestRest DELETE"/>
</form>
springmvc的POST 请求转为 DELETE 或 put 请求配置HiddenHttpMethodFilter
