两个具有相同包名，相同类名和相同方法名的罐子

Question

I am facing this problem in spring boot application where I am using Two jars. And in those jars there are two classes with the same package name and same class name and one method with the same name . Problem occurs when class loader loads the class from different jar and tries to call this method, If jar A is loaded first then method is called and everything works fine , But if jar B is called first then, NOSUCHMETHODERROR exception is thrown at runtime. Can you please help to fix this. Is there a way by which I can force the classloader to load a particular jar first, always in Spring boot app, Or probably any other fix for this.

NOTE: I am using JAVA 8 and I don't have access to the source code of these jar files.

Answer 1

If you are loading those jars as a dependency you could exclude it from Maven via

<exclusions>
   <exclusion>
       <groupId>org.XXXX</groupId>
        <artifactId>jar1-api</artifactId>
    </exclusion>
</exclusions>
