[开发工具]idea+maven+lombok：封装统一的响应类

1 开发环境介绍

1.1 开发工具

idea + maven

1.2 导入依赖 - lombok

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.12</version>
    <scope>provided</scope>
</dependency>

2 工具类代码示例 - - - Result

import lombok.Getter;
import lombok.Setter;

@Getter
@Setter
public class Result<T> {
    private static Integer CODE_SUCCESS = 1;
    private static Integer CODE_ERROR = 0;
    private static String DEFAULT_SUCCESS_MSG = "success";
    private static String DEFAULT_ERROR_MSG = "error";


    private Integer code;
    private T data;
    private String msg;

    private Result() {
    }

    private Result(Integer code, T b, String msg) {
        this.code = code;
        this.data = b;
        this.msg = msg;
    }

    public static <T> Result success() {
        return new Result(CODE_SUCCESS, true, DEFAULT_SUCCESS_MSG);
    }

    public static <T> Result success(T data) {
        return new Result<>(CODE_SUCCESS, data, DEFAULT_SUCCESS_MSG);
    }

    public static <T> Result success(String msg) {
        return new Result<>(CODE_SUCCESS, true, msg);
    }

    public static <T> Result error() {
        return new Result(CODE_ERROR, false, DEFAULT_ERROR_MSG);
    }

    public static <T> Result error(T data) {
        return new Result(CODE_ERROR, data, DEFAULT_ERROR_MSG);
    }

    public static <T> Result error(String msg) {
        return new Result(CODE_ERROR, false, msg);
    }

}

3 工具类测试

3.1 测试工具

postman

3.2 测试代码

使用idea创建一个springboot项目，只选择web即可

@RestController
@RequestMapping("/test")
public class test {

    @GetMapping("/success")
    public Result testUtilResultSuccessDef(){
        return Result.success();
    }

    @GetMapping("/error")
    public Result testUtilResultErrorDef(){
        return Result.error();
    }
}

3.3 测试接口

不做配置的项目，默认启动的端口是8080，因此可采用下述两个接口来测试

• 成功的测试接口示例：127.0.0.1:8080/test/success
• 失败的测试接口示例：127.0.0.1:8080/test/error
