1、PathVariable注解
用于映射url的占位符到目标方法的参数中
例子：
@RequestMapping("/testPathVariable/{id}")
public String testPathVariable(@PathVariable("id") Integer id) {
syso (id);
}
请求：/testPathVariable/101 输出：101
2、REST请求示例：
/order HTTP POST --新增
/order/1 HTTP DELETE --删除
/order/1 HTTP PUT --修改
/order/1 HTTP GET --查看
3、如何发送一个PUT和DELETE请求
1）在web.xml中配置一个filter HiddenHttpMethodFilter。
2）发送一个POST请求
3）在请求参数中放入_method = DELETE 或PUT
配置：
<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>
controller:
@RequestMapping(value="/order/{id}",method=RequestMethod.GET)
public String testGet(@PathVariable Integer id) {
System.out.println("testGet id=" + id);
return SUCCESS;
}
@RequestMapping(value="/order",method=RequestMethod.POST)
public String testPOST() {
System.out.println("testPOST");
return SUCCESS;
}
@RequestMapping(value="/order/{id}",method=RequestMethod.PUT)
public String testPUT(@PathVariable Integer id) {
System.out.println("testPUT id=" + id);
return "redirect:/success.jsp";
}
@RequestMapping(value="/order/{id}",method=RequestMethod.DELETE)
public String testDELETE(@PathVariable Integer id) {
System.out.println("testDELETE id=" + id);
return "redirect:/success.jsp";
}
测试：
<br> <br> <a href="test/order/11">test testGET</a> <br> <br> <form action="test/order" method="post"> <input type="submit" value="testPost"> </form> <br> <br> <form action="test/order/11" method="post"> <input type="hidden" name="_method" value="PUT"> <input type="submit" value="testPUT"> </form> <br> <br> <form action="test/order/11" method="post"> <input type="hidden" name="_method" value="DELETE"> <input type="submit" value="testDELETE"> </form>
注意tomcat8报错：
HTTP Status 405 - JSPs only permit GET POST or HEAD
1、使用低版本tomcat
2、在返回时使用重定向：return "redirect :/test.jsp"
3、写一个Filter来包装HttpRequest中的getMethod()方法
