SpringBoot的入门程序

1. 创建一个springboot工程

2. 创建一个实体类

@data //想相当于@setter、@getter和@tostring替代了setter、getter、tostring方法
@allargsconstructor//全参数构造方法
@noargsconstructor//无参构造方法
public class user {
    private integer id;
    private string name;
    private date birth;
}

 3. 创建controller类

@restcontroller //相当于@controller和@responsebody两个注解
public class usercontroller {

    @requestmapping(value = "/getuser",method = requestmethod.get)
    public user getuser(){
        return new user(1,"jxy",new date());

    }
}

 4. 实体类中注解的相关依赖

<dependency>
            <groupid>org.projectlombok</groupid>
            <artifactid>lombok</artifactid>
            <version>1.18.6</version>
        </dependency>

 容易出现404路径错误，注意路径书写
