springboot项目创建

这是相关依赖项目如果用到Mybatis和数据库MySQL需要勾选

在springboot项目中企业级最终是使用result设计模式返回数据，就是创建一个result类用于接管要返回的各种数据result类的代码

public class Result {
    private int code;
    private String mes;
    private Object data;

    public Result(int code, String mes, Object data) {
        this.code = code;
        this.mes = mes;
        this.data = data;
    }

    public int getCode() {
        return code;
    }

    public void setCode(int code) {
        this.code = code;
    }

    public String getMes() {
        return mes;
    }

    public void setMes(String mes) {
        this.mes = mes;
    }

    public Object getData() {
        return data;
    }

    public void setData(Object data) {
        this.data = data;
    }

    @Override
    public String toString() {
        return "Result{" +
                "code=" + code +
                ", mes='" + mes + '\'' +
                ", data=" + data +
                '}';
    }
}

简单地实例

@RestController
public class Helloworld {
    @RequestMapping("/hello")
    public Result hell(){
        String s="成功"
        
        return new Result(1,"success",s);

    }
}
