SpringMVC中REST功能範例

1.HTML端代碼

<h1>這個以下是測試REST功能區的代碼</h1>
	<form action="/rest/doOrder" method="post">
		<input type="submit" value="DO POST ADD" />
	</form>
	<br>
	<form action="/rest/doOrder/10" method="post">
		<input type="hidden" name="_method" value="PUT" /> 
		<input type="submit" value="DO PUT" />
	</form>
	<br>
	<form action="/rest/doOrder/11" method="post">
		<input type="hidden" name="_method" value="DELETE" /> 
		<input 	type="submit" value="DO DELETE" />
	</form>
	<br>
	<a href="/rest/doOrder/12">測試GET功能</a>

2.Controller代碼

@Controller
@RequestMapping("/rest")
public class RESTDemoController {
	private static final String SUCCESS = "success";

	@RequestMapping(value = "/doOrder", method = RequestMethod.POST)
	public String doAdd() {
		System.out.println("this is do ADD ");
		return SUCCESS;
	}

	@RequestMapping(value = "/doOrder/{id}", method = RequestMethod.PUT)
	public String doPut(@PathVariable Integer id) {
		System.out.println("this is do doPut " + id);
		return SUCCESS;
	}

	@RequestMapping(value = "/doOrder/{id}", method = RequestMethod.DELETE)
	public String doDelete(@PathVariable Integer id) {
		System.out.println("this is do Delete " + id);
		return SUCCESS;
	}

	@RequestMapping(value = "/doOrder/{id}", method = RequestMethod.GET)
	public String doGet(@PathVariable Integer id) {
		System.out.println("this is do Get " + id);
		return SUCCESS;
	}

}

3.web.xml代碼

	<!--
			org.springframework.web.filter.HiddenHttpMethodFilter
			這個是一個將POST請求轉化爲DELETE或POST請求
		-->
	<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>
		

這就ok了
