使用 Minio 客户端的 Spring 启动：okhttp3。RequestBody.create([BLokhttp3/MediaType;)Lokhttp3/RequestBody;不存在错误

Question

我试图通过使用minio客户端在春季启动连接到minio服务器。得到这个错误:

试图调用一个不存在的方法。这次尝试是从以下位置生成的:

io.minio.S3Base.<clinit>(S3Base.java:104)

下面的方法不存在:

okhttp3.RequestBody.create([BLokhttp3/MediaType;)Lokhttp3/RequestBody;

方法的类okhttp3。RequestBody，可从以下位置:

jar:file:/home/user/.m2/repository/com/squareup/okhttp3/okhttp/3.14.4/okhttp-3.14.4.jar!/okhttp3/RequestBody.class

从以下位置加载:

file:/home/user/.m2/repository/com/squareup/okhttp3/okhttp/3.14.4/okhttp-3.14.4.jar

行动:

纠正应用程序的类路径，使其包含okhttp3的单一、兼容版本。RequestBody

进程结束，退出码0

我正在使用java 8。我也尝试过没有在pom.xml文件中添加com.squareup.okhttp3依赖项。

Answer 1

解决方案:尝试覆盖您的pom中的okhttp3.version属性，并将其设置为com.squareup.okhttp3:okhttp依赖项的新版本(4.10.0适用于我)。或者直接显式地设置这个依赖项。或者更确切地说，如果可行的话，尝试更新您的start -parent版本(但不确定这是否适用于java 8)。

推理:maven(或者，在我的例子中，gradle)获取旧版本的okhttp库的原因是，在2.7之前的版本中，这个特定的库版本不幸地固定在spring引导依赖项中:

<okhttp3.version>3.14.9</okhttp3.version>

在2.7中，他们将其更改为4.9.3。

Answer 2

尝试更新spring启动版本。我把2.3.2更新到2.7.0，它可以工作了。
