“Package org.apache.hc.httpclient5.conn.ssl does not exist” on Spring Boot upgrade

Question

我必须升级 Spring Boot 依赖项 2.7.5 --> 3.0.2:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>3.0.2</version>
    <relativePath />
</parent>

pom.xml

目前引用了比较新的版本

HttpClient

，4.5.3：

    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.5.3</version>
    </dependency>

代码使用

org.apache.http

类，现在在 Maven Build 上产生以下错误：

import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.conn.ssl.TrustSelfSignedStrategy;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.ssl.SSLContextBuilder;

--> 不兼容的类型：org.apache.http.impl.client.CloseableHttpClient 无法转换为 org.apache.hc.client5.http.classic.HttpClient

为了解决这个错误，我将所有出现的

org.apache.http

替换为

org.apache.hc.httpclient5

每https://hc.apache.org/httpcomponents-client-5.2.x/migration-guide/migration-to-classic.html :

import org.apache.hc.httpclient5.conn.ssl.SSLConnectionSocketFactory;
import org.apache.hc.httpclient5.conn.ssl.TrustSelfSignedStrategy;
import org.apache.hc.httpclient5.impl.client.CloseableHttpClient;
import org.apache.hc.httpclient5.impl.client.HttpClients;
import org.apache.hc.httpclient5.ssl.SSLContextBuilder;

但是现在错误是 包 org.apache.hc.httpclient5.conn.ssl 不存在。它无法解析 HC5 包。有小费吗？

注意：我也尝试用新的 httpclient5 依赖项替换 HttpClient 依赖项，但它是同样的错误：

<dependency>
    <groupId>org.apache.httpcomponents.client5</groupId>
    <artifactId>httpclient5</artifactId>
    <version>5.2.1</version>
</dependency>

Answer 1

org.apache.hc.httpclient5.

的进口要略有不同，如下：

import org.apache.hc.client5.http.ssl.SSLConnectionSocketFactory;
import org.apache.hc.client5.http.ssl.TrustSelfSignedStrategy;
import org.apache.hc.core5.ssl.SSLContextBuilder;
import org.apache.hc.client5.http.impl.classic.CloseableHttpClient;
import org.apache.hc.client5.http.impl.classic.HttpClients;

而不是

import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.conn.ssl.TrustSelfSignedStrategy;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.ssl.SSLContextBuilder;
