[SpringMVC]REST风格CRUD(模板)

Rest风格

在web.xml里写过滤器

<!-- 配置过滤器 作用是把Post请求转换 -->
	<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>

注意：put和delete请求时需要在表单中添加隐藏域的，并且name="_Method"

	@RequestMapping(value = "/testRest/{id}", method = RequestMethod.GET)
	public String testRestGet(@PathVariable Integer id) {
		System.out.println("GET :" + id);
		return SUCCESS;
	}

	@RequestMapping(value = "/testRest", method = RequestMethod.POST)
	public String testRestPost() {
		System.out.println("POST");
		return SUCCESS;
	}

	@RequestMapping(value = "/testRest/{id}", method = RequestMethod.DELETE)
	public String testResDeletet(@PathVariable Integer id) {
		System.out.println("Delete :"+id);
		return SUCCESS;
	}
	
	@RequestMapping(value = "/testRest/{id}", method = RequestMethod.PUT)
	public String testResPut(@PathVariable Integer id) {
		System.out.println("PUT  :"+id);
		return SUCCESS;
	}
