使用Spring Data Commons的Page.map方法时遇异常及Jar执行报错求助

Hey there, let's tackle this method signature mismatch issue you're facing. That error (Lorg/springframework/core/type/AnnotationMetadata;Ljava/lang/Class;Lorg/springframework/core/io/ResourceLoader;Lorg/springframework/core/env/Environment;)V almost always points to a Spring version conflict—different parts of your project are pulling in incompatible versions of Spring framework components. Here's how to resolve it step by step:

1. Verify Spring Version Consistency #

• Since you're using a parent dependency (like spring-boot-starter-parent), it should manage most Spring-related dependency versions automatically. Double-check that any Spring dependencies you added manually don't specify a version that clashes with the parent's managed version.
• Run the Maven command to inspect your dependency tree and spot conflicting versions:

  mvn dependency:tree
  

  Look for entries of org.springframework:spring-core, org.springframework:spring-context, or related packages with mismatched versions (e.g., one using 5.3.x and another using 6.0.x).

2. Exclude Conflicting Dependencies #

If the dependency tree reveals a third-party library pulling in an older or incompatible Spring version, add exclusions to that dependency in your pom.xml to force it to use the parent-managed version. For example:

<dependency>
    <groupId>com.example.thirdparty</groupId>
    <artifactId>problematic-library</artifactId>
    <version>1.0.0</version>
    <exclusions>
        <exclusion>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
        </exclusion>
    </exclusions>
</dependency>

3. Rebuild and Test #

• Clean and rebuild your project to ensure all dependencies are resolved correctly:

  mvn clean install
  

• Run your JAR again to see if the exception is resolved. If not, recheck the dependency tree for any remaining version conflicts.

4. Additional Checks #

• Confirm your parent dependency is correctly configured. For Spring Boot projects, ensure your parent is:

  <parent>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-parent</artifactId>
      <version>your-stable-version</version>
      <relativePath/>
  </parent>
  

  Make sure the parent version aligns with your Java runtime (Spring Boot 3.x requires Java 17+, while 2.x supports Java 8-17).
• Avoid manually specifying versions for Spring core components unless absolutely necessary—let the parent dependency handle version management to prevent mismatches.
