一、SpringBoot Controller 接收请求参数——URL参数接收（get与post方法通用）

1.通过@PathVariable注解获取URL请求参数

/**
     * 通过@PathVariable获取URL中的参数
     * @param username
     * @param password
     * @return
     */
    @RequestMapping(value="/test/{username}/{password}")
public String addUser4(@PathVariable String username,@PathVariable String password) {
        System.out.println("username is:"+username);
        System.out.println("password is:"+password);
		return null;
    }

2.通过JavaBean接收

Javabean：

public class UserModel {
    
    private String username;
    private String password;
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    
}

Controller：

 /**
     * @param user
     * @return
     */
    @RequestMapping("/test")
    public String addUser3(UserModel user) {
        System.out.println("username is:"+user.getUsername());
        System.out.println("password is:"+user.getPassword());
        return null;
    }

3.通过@RequestParam注解接收

 /**
     * 通过@RequestParam绑定请求参数到方法入参
     * @param username
     * @param password
     * @return
     */
    @RequestMapping(value="/test")
    public String addUser6(@RequestParam("username") String username,@RequestParam("password") String password) {
        System.out.println("username is:"+username);
        System.out.println("password is:"+password);
        return null;
    }

二、SpringBoot Controller 接收请求参数——Post参数

1.JavaBean 配合 @RequestBody注解接收参数

JavaBean：

public class UserModel {
    
    private String username;
    private String password;
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    
}

Controller：

 /**
     * @param user
     * @return
     */
    @RequestMapping("/test")
    public String addUser3(@RequestBody UserModel user) {
        System.out.println("username is:"+user.getUsername());
        System.out.println("password is:"+user.getPassword());
        return null;
    }

2.fastjson配合@RequestBody注解接收JSON对象参数

 /**
     * @param user
     * @return
     */
    @RequestMapping("/test")
    public String addUser3(@RequestBody  JSONObject user) {
        System.out.println("username is:"+user.getString("userName"));
        System.out.println("password is:"+user.getString("passWord"));
        return null;
    }
