找不到 org.apache.http.annotation.NotThreadSafe 的类文件，我该如何在 Intellij 想法上修复它？

Question

message:javac 1.8.0_172 was used to compile java sources
error:java: 
Inaccessible org.apache.http.annotation.NotThreadSafe
Can not found class file of org.apache.http.annotation.NotThreadSafe

C:...\common\HttpUtils.java 
warn:java:
org.apache.http.impl.client's org.apache.http.impl.client.DefaultHttpClient is obsolete

Thanks in advance. I am searching for a long time on the net. But no use. Please help or try to give some ideas how to achieve this.

Answer 1

Solution can be found here for the error.

DefaultHttpClient is deprecated, you can this solution here to import the Java HttpClient.

Answer 2

根据此所述@NotThreadSafe注释应改为@Contract (threading = org.apache.http.annotation.ThreadingBehavior.UNSAFE)它使用org.apache.http.annotation.Contract 。

Answer 3

Try using 4.5.2 httpclient to 4.4.4 httpcore.
