升级到2.2.4: method后无法运行Spring应用程序

Question

在将Spring版本从2.1.11升级到2.2.4后，我得到了一个错误。然后，我将openfeign从2.0.2升级到2.2.1，但这并没有帮助。

不存在以下方法：

'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

它从以下位置加载：

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。旧版本仍然公开了这个使用int参数的方法，但是已经声明了它是不推荐的，您应该使用java.time.Duration。

接受java.time.Duration的方法在2.2.4中仍然存在，您应该使用该方法。

Answer 2

似乎setConnectTimeout(int connectTimeout)已被废弃，而setConnectTimeout(Duration connectTimeout)则是added.Please，尝试添加以下内容
