java Tomcat 7 注释扫描器和带有 -parameters 编译器标志异常的 JDK 8

Tomcat 7 Annotation scanner and JDK 8 with -parameters compiler flag exceptions

提问by Gerrit Brink

I am compiling my classfiles with JDK 8 with the -parameters flag which preserves the parameter names and makes them available via reflection. Tomcat 7 seems to have issues with my class files.

我正在使用带有 -parameters 标志的 JDK 8 编译我的类文件，该标志保留参数名称并通过反射使它们可用。Tomcat 7 似乎对我的类文件有问题。

I have got the same problem and I resolved it without upgrading tomcat version as the following:

我遇到了同样的问题，我在没有升级 tomcat 版本的情况下解决了它，如下所示：

1. Changing the jaassist version ( i used the version 3.20.0-GA and i changed it to 3.18.1-GA)

2. adding some args to maven compiler plugin

   <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-compiler-plugin</artifactId>
       <version>${plugin.compiler.version}</version>
       <configuration>
           <source>${project.build.javaVersion}</source>
           <target>${project.build.javaVersion}</target>
           <forceJavacCompilerUse>true</forceJavacCompilerUse>
           <fork>true</fork>
           <compilerArgument>-proc:none</compilerArgument>             
       </configuration>
   </plugin>
   

3. adding the tag metadata-complete="true" to the web.xml

1. 更改 jaassist 版本（我使用了 3.20.0-GA 版本，然后将其更改为 3.18.1-GA）

2. 向 Maven 编译器插件添加一些参数

   <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-compiler-plugin</artifactId>
       <version>${plugin.compiler.version}</version>
       <configuration>
           <source>${project.build.javaVersion}</source>
           <target>${project.build.javaVersion}</target>
           <forceJavacCompilerUse>true</forceJavacCompilerUse>
           <fork>true</fork>
           <compilerArgument>-proc:none</compilerArgument>             
       </configuration>
   </plugin>
   

3. 将标签 metadata-complete="true" 添加到 web.xml

That is correct, you have to disableannotation processing, see this question org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 15for more information.

没错，您必须禁用注释处理，请参阅此问题org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 15了解更多信息。
