对于类没有工作的动画，Aspectj [英] Aspectj for anotations with classes not working

问题描述

以下代码未正确使用aspectJ

  import org.springframework.context.annotation .ConditionContext; 
 import org.springframework.context.annotation.Conditional; 
 import org.springframework.context.annotation.Configuration; 
 import org.springframework.context.annotation.ConfigurationCondition; 
 import org.springframework.context.annotation.ImportResource; 
 import org.springframework.core.type.AnnotatedTypeMetadata; 
 
 @Configuration 
 @Conditional（ConditionalConfiguration.Condition）
 @ImportResource（/ com / example / context-fragment.xml）
 public class ConditionalConfiguration {
 static class Condition实现ConfigurationCondition {
 @Override 
 
 public ConfigurationPhase getConfigurationPhase（）{
 return ConfigurationPhase.PARSE_CONFIGURATION; 
} 
 @Override 
 public boolean matches（ConditionContext context，AnnotatedTypeMetadata metadata）{
 //仅在系统属性定义时才加载context-fragment.xml 
返回System.getProperty（com.example.context-fragment）！= null; 
} 
} 
} 
  

我正在使用Eclipse Aspectj工具。并且错误显示为 @Conditional 注释。

正如 @Conditional

  @Retention（RetentionPolicy.RUNTIME）
 @ Target（{ElementType.TYPE，ElementType.METHOD}）
 public @interface条件{
 
 / ** 
 *所有{@link条件}必须{@linkplain条件#matches match} 
 *，以便组件被注册。 
 * / 
 Class<？ extends Condition> [] value（）; 
 
} 
  

错误是：

  org.aspectj.weaver.BCException 
在org.aspectj.ajdt.internal.core.builder.AjState.recordClassFile （AjState.java:1519）
在org.aspectj.ajdt.internal.core.builder.AjState.noteResult（AjState.java:1325）
在org.aspectj.ajdt.internal.core.builder .AjBuildManager $ 3.acceptResult（AjBuildManager.java:1061）
在org.aspectj.ajdt.internal.compiler.AjPipeliningCompilerAdapter.afterProcessing（AjPipeliningCompilerAdapter.java:426）
在org.aspectj.ajdt.intern。 .. .0_21-64\jre\lib\ext\sunmscapi.jar; E：\jdk1.7.0_21-64\jre\lib\ext\zipfs.jar; D：\ eclipse\\plugins / org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar; 
  

任何想法如何使其工作，或至少是一种我可以设置Eclipse的方式AspectJ Tool简单地忽略这个文件。

解决方案

我只是能够重现你的问题。你的代码是错误的，而不是AspectJ。更改您的注释值：

  @Conditional（ConditionalConfiguration.Condition.class）
  

你只是忘了使用 .class 后缀。修复你自己的代码，那么编译器就不会再抱怨了。

更新：因为你的错误不应该杀死AspectJ编译器，所以我创建了一个 bug ticket ，但事实依然是你自己的代码是伪造的。 / p>

Below code is not complied correctly with aspectJ

import org.springframework.context.annotation.ConditionContext;
import org.springframework.context.annotation.Conditional;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ConfigurationCondition;
import org.springframework.context.annotation.ImportResource;
import org.springframework.core.type.AnnotatedTypeMetadata;

@Configuration
@Conditional(ConditionalConfiguration.Condition)
@ImportResource("/com/example/context-fragment.xml")
public class ConditionalConfiguration {
    static class Condition implements ConfigurationCondition {
         @Override  

         public ConfigurationPhase getConfigurationPhase() {
             return ConfigurationPhase.PARSE_CONFIGURATION;
         }          
         @Override
         public boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata) {
             // only load context-fragment.xml if the system property is defined
             return System.getProperty("com.example.context-fragment") != null;
         }
    }
}

I am using Eclipse Aspectj Tool. and the error is shown for @Conditional annotation.

The is as @Conditional:

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.TYPE, ElementType.METHOD})
public @interface Conditional {

    /**
     * All {@link Condition}s that must {@linkplain Condition#matches match}
     * in order for the component to be registered.
     */
    Class<? extends Condition>[] value();

}

The error is:

org.aspectj.weaver.BCException
at org.aspectj.ajdt.internal.core.builder.AjState.recordClassFile(AjState.java:1519)
at org.aspectj.ajdt.internal.core.builder.AjState.noteResult(AjState.java:1325)
at org.aspectj.ajdt.internal.core.builder.AjBuildManager$3.acceptResult(AjBuildManager.java:1061)
at org.aspectj.ajdt.internal.compiler.AjPipeliningCompilerAdapter.afterProcessing(AjPipeliningCompilerAdapter.java:426)
at org.aspectj.ajdt.intern ... .0_21-64\jre\lib\ext\sunmscapi.jar;E:\jdk1.7.0_21-64\jre\lib\ext\zipfs.jar;D:\eclipse\\plugins/org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar;

Any Idea how can I make it work, Or at least is it a way which I can set Eclipse AspectJ Tool to simply ignore this file.

解决方案

I was just able to reproduce your problem. Your code is wrong, not AspectJ. Change your annotation value like this:

@Conditional(ConditionalConfiguration.Condition.class)

You just forgot to use the .class suffix. Fix your own code, then the compiler will not complain anymore. ;-)

Update: Because your bug should not kill the AspectJ compiler anyway, I created a bug ticket for it, but the fact remains that your own code was bogus.
