1.基于SpringBoot3+JDK17+Gradle8搭建项目

获取代码请关注公众号 算法小生，回复cloud即可，不懂的欢迎加群沟通

1. 环境准备

• IDEA2023
• JDK17
• Gradle8

2. 多模块项目创建

我们删除src目录，如下图所示

我们新建模块api、common、client，并删除无用内容，结果如下

3. 依赖修改

我们修改父模块build.gradle中内容如下

plugins {
    id 'java'
    id 'org.springframework.boot' version '3.1.0'
    id 'io.spring.dependency-management' version '1.1.0'
}

archivesBaseName = "cloud-api"

bootJar.enabled = true

// 版本信息
ext {
    set('springCloudVersion', "2022.0.3")
    lombokVersion = '1.18.26'
}

// 通用配置
subprojects {
    // 使用插件
    apply plugin: 'java'
    apply plugin: 'org.springframework.boot'
    apply plugin: 'io.spring.dependency-management'

    // 项目默认名称与版本
    group = 'online.shenjian'
    version = '1.0-SNAPSHOT'

    tasks.withType(JavaCompile) {
        options.encoding = "UTF-8"
    }

    // 指定JDK版本
    sourceCompatibility = '17'
    jar.enabled = true

    // 指定仓库地址
    repositories {
        mavenLocal()
        mavenCentral()
    }

    dependencyManagement {
        // 导入SpringBoot和SpringCloud依赖Bom
        imports {
            mavenBom org.springframework.boot.gradle.plugin.SpringBootPlugin.BOM_COORDINATES
            mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
        }
    }
}

我们修改common中build.gradle内容如下

archivesBaseName = "common"

// 取消打包为 bootJar 可独立运行包，因为 common 只是一个普通的jar包
// 如果是需要独立运行的jar包，这个就改为true
bootJar.enabled = false

dependencies {

    compileOnly 'org.projectlombok:lombok:1.18.28'
    annotationProcessor 'org.projectlombok:lombok:1.18.28'
    implementation 'com.alibaba:fastjson:2.0.35'
    implementation 'cn.hutool:hutool-core:5.8.20'
    implementation 'org.apache.commons:commons-lang3:3.12.0'
}

我们修改client中build.gradle内容如下

archivesBaseName = "client"

bootJar.enabled = false

dependencies {

    implementation 'org.springframework.cloud:spring-cloud-starter-openfeign'
    implementation 'org.springdoc:springdoc-openapi-starter-webmvc-ui:2.1.0'
    implementation 'org.springdoc:springdoc-openapi-starter-webmvc-api:2.1.0'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    compileOnly 'org.projectlombok:lombok:1.18.28'
    annotationProcessor 'org.projectlombok:lombok:1.18.28'

}

我们修改api中build.gradle内容如下

archivesBaseName = "api"

bootJar.enabled = true

dependencies {

    implementation 'org.springframework.boot:spring-boot-starter'
    implementation 'org.springframework.cloud:spring-cloud-starter-bootstrap'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.apache.commons:commons-lang3:3.12.0'

    implementation 'org.springdoc:springdoc-openapi-starter-webmvc-ui:2.1.0'
    implementation 'org.springdoc:springdoc-openapi-starter-webmvc-api:2.1.0'
    implementation 'com.alibaba:fastjson:2.0.35'
    implementation 'com.nimbusds:nimbus-jose-jwt:9.31'

    implementation 'com.mysql:mysql-connector-j'
    implementation 'com.alibaba:druid-spring-boot-3-starter:1.2.18'

    implementation 'org.springframework.boot:spring-boot-starter-test'

    compileOnly 'org.projectlombok:lombok:1.18.28'
    annotationProcessor 'org.projectlombok:lombok:1.18.28'

    implementation 'cn.hutool:hutool-core:5.8.20'

    // 本地方法调用依赖
    implementation 'net.java.dev.jna:jna:5.13.0'

    // 引入本地的 common 模块
    implementation project(':common')
    implementation project(':client')

    testImplementation 'junit:junit:4.13.1'
}

我们点击gradle刷新按钮，耐心等待相关文件下载

4. client模块代码编写

我们新建文件，结构如下

ResponseCode.java代码如下

public enum ResponseCode {

    SUCCESS(200, "成功"),
    FAIL(-1, "失败"),
    UN_AUTHORIZED(401, "用户未授权,请联系管理员"),
    TOKEN_EXPIRATION(402, "登录已过期,请退出后重新登录"),

    LICENSE_EXPIRED(403, "授权已失效");

    private Integer val;
    private String des;

    ResponseCode(Integer val, String des) {
        this.val = val;
        this.des = des;
    }

    public Integer val() {
        return val;
    }

    public String des() {
        return des;
    }
}

ResponseVO.java代码如下

@Data
public class ResponseVo<T> implements Serializable {

    private Integer code;
    private String message;
    private T data;

    public static ResponseVo message(int code, String message) {
        ResponseVo responseVo = new ResponseVo();
        responseVo.setCode(code);
        responseVo.setMessage(message);
        return responseVo;
    }

    public static ResponseVo message(ResponseCode responseCode) {
        ResponseVo responseVo = message(responseCode.val(), responseCode.des());
        return responseVo;
    }

    public static ResponseVo message(int code, String message, Object data) {
        ResponseVo responseVo = new ResponseVo();
        responseVo.setCode(code);
        responseVo.setMessage(message);
        responseVo.setData(data);
        return responseVo;
    }

    public static ResponseVo success() {
        ResponseVo responseVo = new ResponseVo();
        responseVo.setCode(ResponseCode.SUCCESS.val());
        return responseVo;
    }

    public static ResponseVo success(Object data) {
        ResponseVo responseVo = new ResponseVo();
        responseVo.setCode(ResponseCode.SUCCESS.val());
        responseVo.setData(data);
        return responseVo;
    }

    public static ResponseVo error(String message) {
        ResponseVo responseVo = new ResponseVo();
        responseVo.setCode(ResponseCode.FAIL.val());
        responseVo.setMessage(message);
        return responseVo;
    }
}

UserInfoDto.java代码如下

@Schema(description = "用户信息DTO")
@Data
public class UserInfoDto {

    @Schema(description = "用户ID")
    private String userId;

    @Schema(description = "用户名")
    private String username;

    @Schema(description = "登录账号")
    private String account;

    @Schema(description = "密码")
    private String password;

    @Schema(description = "机构编码")
    private String orgCode;

    @Schema(description = "机构名称")
    private String orgName;

    @Schema(description = "角色ID")
    private String roleId;

    @Schema(description = "用户角色")
    private String roleName;
}

CloudClient.java代码如下

@FeignClient(value = "cloud", contextId = "cloud")
@Component
public interface CloudClient {

    @PostMapping(value = "/login", produces = MediaType.APPLICATION_JSON_VALUE)
    @Operation(summary = "登录", tags = "用户管理")
    ResponseVo login(@RequestBody UserInfoDto userInfoDto);
}

5. api模块代码编写

新建CloudController.java类，代码如下

@RestController
public class CloudController implements CloudClient {

    @Override
    public ResponseVo login(UserInfoDto userInfoDto) {
        return ResponseVo.success("登录成功");
    }
}

新建CloudApplication.java类，代码如下

@SpringBootApplication
public class CloudApplication {

    public static void main(String[] args) {
        SpringApplication.run(CloudApplication.class, args);
    }
}

新建bootstrap.yml，代码如下

spring:
  application:
    name: cloud
  profiles:
    active: dev

6. 运行并响应

我们点击CloudApplication.java中run按钮，然后用apifox工具进行请求，success
