jdk21好像不能用

[xingmu]

方法上配置@Before(Interceptor.class)就报错了

[litongjava]

你把详细的错误发一下呀。 还没有对jdk21适配。 你的版本号也发一下。

已解决,测试成功

Before Aspect1 invoking
cat eat
After Aspect1 invoking

请更新到v1.0.8

    <dependency>
      <groupId>com.litongjava</groupId>
      <artifactId>jfinal-aop</artifactId>
      <version>1.0.8</version>
    </dependency>

测试代码和工程

https://github.com/litongjava/java-ee-tio-boot-study/tree/main/jfinal-aop-study/src/main/java/com/issues01

复测成功后请关闭该issuue

[litongjava]

set JAVA_HOME=D:\\java\\jdk1.8.0_121
mvn clean install -DskipTests -Dgpg.skip

推送失败,下载安装到本地吧

[xingmu]

我环境变量配置的jdk21，包括pom里，编译都指定的是21。 我对底层的知识不太了解，还请指点。

[litongjava]

请问你升级了吗？有没有升到1.0.8版本？

[xingmu]

升级了

[litongjava]

你切到到jdk8看一下是否报错?

我测试了N遍,Jdk 21正常.

java-version:21.0.1
Before Aspect1 invoking
cat eat
After Aspect1 invoking

要不你下载这个工程测试一下 https://github.com/litongjava/java-ee-tio-boot-study/tree/main/jfinal-aop-study/

[litongjava]

你的反馈要写的规范一些 代码和和错误日志要分开,有问题在和我联系

[xingmu]

估计还是我的配置有问题，我把你的项目下载下来看看 我的pom.xml

    <properties>
        <java.version>21</java.version>
        <maven.compiler.source>${java.version}</maven.compiler.source>

        </dependency>
    </dependencies>

系统环境变量、idea、maven、编译器、项目模块、sdk等都设置的21

代码没变，运行报错
