我的第一个springboot接口项目-创新互联

1. idea创建项目

勾选web-spring web依赖

创建新的类，拼接url

启动
@SpringBootApplication

postman调用接口http://localhost:8080/h1/h2

1. 带有参数的接口

package com.example.demo;

import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/h1")
public class http {@RequestMapping("/h2")
    public String toweb(@RequestBody Test param){System.out.println(param.getAge()+"&&&");
        System.out.println(param.getName()+"****");
        System.out.println("sucess"+param);
        return "hello";
    }
}

Test是自定义的类，

package com.example.demo;

public class Test {int age;
    String name;

    @Override
    public String toString() {return "Test{" +
                "age=" + age +
                ", name='" + name + '\'' +
                '}';
    }

    public void setAge(int age) {this.age = age;
    }

    public void setName(String name) {this.name = name;
    }

    public int getAge() {return age;
    }

    public String getName() {return name;
    }

    public Test(int age, String name) {this.age = age;
        this.name = name;
    }
}

postmen里面的json字段要和类的属性一致，否则获取到null,如果不加@RequestBody，则
可以获取到form-data和x-www-form-urlencoded

@GetMapping("/goods/{id}")
    public Goods goods(@PathVariable(name = "id") Integer id) {Goods g = new Goods(id, "草莓", 6.5, new Date(), "好吃");
        return g;
    }

@RestController
@RequestMapping("/h1")
public class http {@RequestMapping("/h2/{id}")
    @ResponseBody
    public String toweb(@PathVariable(name = "id") Integer id){System.out.println(id+"&&&");
        System.out.println("sucess");
        return "543";
    }
}
