升级到 2.2.4 后无法运行 Spring Boot 应用：方法不存在

Question

将 Spring Boot 版本从 2.1.11 升级到 2.2.4 后出现错误。然后我把 spring-cloud-starter-openfeign 从 2.0.2 升级到了 2.2.1，但是没有用。

以下方法不存在：

'org.springframework.boot.web.client.RestTemplateBuilder org.springframework.boot.web.client.RestTemplateBuilder.setConnectTimeout(int)'

该方法的类 org.springframework.boot.web.client.RestTemplateBuilder 可从以下位置获得：

jar:file:/C:/Users/a/.gradle/caches/modules-2/files-2.1/org.springframework.boot/spring-boot/2.2.4.RELEASE/225a4fd31156c254e3bb92adb42ee8c6de812714/spring-boot-2.2.4.RELEASE.jar!/org/springframework/boot/web/client/RestTemplateBuilder.class

它是从以下位置加载的：

file:/C:/Users/a/.gradle/caches/modules-2/files-2.1/org.springframework.boot/spring-boot/2.2.4.RELEASE/225a4fd31156c254e3bb92adb42ee8c6de812714/spring-boot-2.2.4.RELEASE.jar

调用方法的尝试发生在自定义类的构造函数中

 this.restTemplate = restTemplateBuilder.setConnectTimeout(props.getConnectTimeoutMs()).setReadTimeout(props.getReadTimeoutMs()).build();

build.gradle：

buildscript {
    repositories {...
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:2.2.4.RELEASE")

Answer 1

分别查看2.1.11 和2.2.4 版本的Javadoc。旧版本仍然公开此方法采用 int 参数，但已经声明它已被弃用，您应该改用 java.time.Duration。

接受java.time.Duration 的方法在 2.2.4 中仍然存在，您应该改用那个方法。

Answer 2

似乎setConnectTimeout(int connectTimeout) 已被弃用，而是添加了setConnectTimeout(Duration connectTimeout)。请尝试添加此
