本文介绍了EJB测试用TomEE嵌入EJBContainer api:java.lang.ClassFormatError异常的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述



这是我的JUnit测试用例框架:

  package com.xxx.indexer.scheduler.service; 

import java.util.Properties;

import javax.ejb.embeddable.EJBContainer;
import javax.naming.NamingException;

import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;

import com.xxx.indexer.scheduler.AbstractTest;

public class BookingAuditServiceImplTest extends AbstractTest {

private static EJBContainer container;

@BeforeClass
public static void start(){
final属性props = new Properties();
props.setProperty(EJBContainer.PROVIDER,tomee-embedded);
container = EJBContainer.createEJBContainer(props);
}

@AfterClass
public static void stop(){
container.close();
}

@Before
public void inject()throws NamingException {
container.getContext()。bind(inject,this);
}

@Test
public void test(){
// TODO
}

}

这些是我的maven依赖:

 <依赖性> 
< groupId> junit< / groupId>
< artifactId> junit< / artifactId>
< version> 4.10< / version>
< scope> test< / scope>
< / dependency>

< artifactId> tomee-embedded< / artifactId>
< version> 1.0.0< / version>

当我启动测试类时,EJBContainer.createEJBContainer()方法抛出一个java.lang.ClassFormatError例外:

  java.lang.ClassFormatError:在类文件中不是本机或抽象的方法中缺少代码属性javax / ejb / java.lang.ClassLoader.defineClass1(Native Method)中的可嵌入/ EJBContainer

我如何做?

解决方案

我在这个链接中阅读,问题是maven依赖的顺序。



我必须先声明tomee嵌入的工件,并在javaee api之后,以这种方式:

 < dependency> 
< groupId> org.apache.openejb< / groupId>
< artifactId> tomee-embedded< / artifactId>
< version> 1.0.0< / version>
< scope> test< / scope>
< / dependency>
<依赖关系>
< groupId> javax< / groupId>
< artifactId> javaee-api< / artifactId>
< version> 6.0< / version>
< scope>已提供< / scope>
< / dependency>

它的作品。


I would test my EJB with TomEE embedded EJBContainer.

This is my JUnit test case skeleton:

package com.xxx.indexer.scheduler.service;

import java.util.Properties;

import javax.ejb.embeddable.EJBContainer;
import javax.naming.NamingException;

import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;

import com.xxx.indexer.scheduler.AbstractTest;

public class BookingAuditServiceImplTest extends AbstractTest {

    private static EJBContainer container;

    @BeforeClass
    public static void start() {
        final Properties props = new Properties();
        props.setProperty(EJBContainer.PROVIDER, "tomee-embedded");
        container = EJBContainer.createEJBContainer(props);
    }

    @AfterClass
    public static void stop() {
        container.close();
    }

    @Before
    public void inject() throws NamingException {
        container.getContext().bind("inject", this);
    }

    @Test
    public void test() {
        // TODO
    }

}

And these are my maven dependecies:

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.10</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>javax</groupId>
  <artifactId>javaee-api</artifactId>
  <version>6.0</version>
  <scope>provided</scope>
</dependency>
<dependency>
  <groupId>org.apache.openejb</groupId>
  <artifactId>tomee-embedded</artifactId>
  <version>1.0.0</version>
  <scope>test</scope>
</dependency>

When I start the test class, the EJBContainer.createEJBContainer() method throws a java.lang.ClassFormatError exception:

How can I do?

解决方案

I read at this link, https://stackoverflow.com/a/3416368/1412839, that the problem is the order of maven dependencies.

I have to declare first the tomee embedded artifact, and after the javaee api, in this way:

<dependency>
  <groupId>org.apache.openejb</groupId>
  <artifactId>tomee-embedded</artifactId>
  <version>1.0.0</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>javax</groupId>
  <artifactId>javaee-api</artifactId>
  <version>6.0</version>
  <scope>provided</scope>
</dependency>

It works.
