创建子模块：fine-commons

• 在fine-parent中创建：fine-commons子模块

fine-commons

• 创建子模块：New > Module...
• 添加公共组件的依赖
• 维护工具类
• 添加接口文档插件，打包工具类文档

依赖、添加接口文档插件

• fine-commons/pom.xml

打包接口文档

• install同步在fine-commons/target/apidocs下生成文档

维护父工程：fine-parent

fine-parent

• 添加该子模块
• 在父工程中，管理版本参数

pom

• fine-parent/pom.xml

<!-- 版本参数 -->
<properties>
    <!-- fine-commons -->
    <fastjson.version>2.0.57</fastjson.version>
    <hutool.version>5.8.23</hutool.version>
    <apache.commons.version>3.14.0</apache.commons.version>
    <oshi.version>6.8.1</oshi.version>
    <lombok.version>1.18.30</lombok.version>
</properties>

fine-commons使用

网络请求

RestTemplate

// 创建对象
private static final RestTemplate restTemplate = new RestTemplate();

// get请求
public void get() {
    // 请求路径
    String url = "http://127.0.0.1:8080/get?arr=[]&obj={}";
    // 请求头
    HttpHeaders headers = new HttpHeaders();
    // 添加Cookie，注意这里的格式应该是 "name=value; name2=value2"
    headers.add(HttpHeaders.COOKIE, "JSESSIONID="+getJSessionId());
    // 创建HttpEntity对象
    HttpEntity<String> entity = new HttpEntity<>("parameters", headers);
    // 发生请求
    ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.GET, entity, String.class);
    if (response.getStatusCode() == HttpStatus.OK) {
        System.out.println(response.getBody());
    }else {
        throw new RuntimeException("查询失败");
    }
}

RestUtils

• 内部也是基于RestTemplate

// get请求
String url = "http://127.0.0.1:8080/get?arr=[]&obj={}";
try {
    ResponseEntity<Result> response = RestUtils.get(url, Result.class);
    if (response.getStatusCode() == HttpStatus.OK ) {
        System.out.println(response.getBody());
    }else{
        return new Result(ResultCodes.ERROR, "接口异常：" + url, "获取应用详情失败.");
    }
}catch (Exception e){
    return new Result(ResultCodes.ERROR, "接口异常：" + url, "获取应用详情失败.");
}

// post请求
String url = "http://127.0.0.1:8080/post";
Map<String, String> params = Map.of(
        "arr", "[]",
        "obj", "{}"
);
try {
    ResponseEntity<Result> response = RestUtils.postForm(url, params, Result.class);
    if (response.getStatusCode() == HttpStatus.OK ) {
        System.out.println(response.getBody());
    }else{
        return new Result(ResultCodes.ERROR, "接口异常：" + url, "获取应用详情失败.");
    }
}catch (Exception e){
    return new Result(ResultCodes.ERROR, "接口异常：" + url, "获取应用详情失败.");
}
