简单路由接口

在main.java包下创建

风格熟悉的控制类
[TestController.java]

package com.demo;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {
	@RequestMapping(value = "/print")
	public String print(){
		return "Hello Controller!";
	}
}

浏览器访问无误 http://localhost:8080/print
--------------------------------------------------------------------
GET-URL带参数方式1

import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {
	@RequestMapping(value = "/{name}/print/" , method = RequestMethod.GET)
	public String print(@PathVariable("name") String name){
		return "WelCome:"+name;
	}
}

浏览器测试:http://localhost:8080/s/print/

POST-带参方式

import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {
	@RequestMapping(value = "/print/{name}" , method = RequestMethod.POST)
	public String print(@PathVariable("name") String name){
		return "WelCome:"+name;
	}
}

浏览器测试:http://localhost:8080/print/s

其他方式获取Request Scope Parameter

import org.springframework.web.bind.annotation.RequestParam;
@RestController
public class TestController {
	@RequestMapping(value = "/print" , method = RequestMethod.GET)
	public String print(@RequestParam("name") String name){
		return "WelCome:"+name;
	}
}

测试:http://localhost:8080/print?name=123

重定向跳转页面方式

resources/目录下
创建/templates/

放入需要跳转的页面 hello.html

import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@ResponseBody
public class TestController {
	@RequestMapping(value = "/print" , method = RequestMethod.GET)
	public String print(){
		return "hello";
	}
}

测试即可跳转

不同路由访问同一返回

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
@ResponseBody
public class TestController {
	@RequestMapping(value = {"/print","/hello"} , method = RequestMethod.GET)
	public String print(){
		return "hello";
	}
}
