PoweMock集成Spring-test 测试静态方法 禁用字节码验证 -noverify -XX:-UseSplitVerifier

1. 问题 我们使用Spring-test的时候使用如下的代码

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations={"classpath:springmvc-servlet-test.xml", "classpath:application-context-datasource-test.xml",
        "classpath:springbeans/mq-beans-test.xml","classpath:springbeans/ws-beans-test.xml","classpath:springbeans/task-beans-test.xml", "classpath:springbeans/threadpool-beans-test.xml"})
public class JUnitServiceBase extends AbstractJUnit4SpringContextTests {
}

然后测试类，直接继承这个class就可以直接的跑起来我们的spring框架啦，这个是没得错的，但是有一点小的问题，我们在模拟PowerMock也是需要一个@RunWith(PowerMockRunner.class)这两个是不可以同时的存在的。@RunWith(SpringJUnit4ClassRunner.class) 这个在高版本的Powemok中，做了一些改进也是希望解决这个问题。我们先看看我们的PowerMock的配置吧！

在官方文档的例子中我们可以看到解决这个问题的办法啦！ 
在测试的时候，在测试类上面加上如下的注解，是可以解决问题的

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
//这个和之前的RunWith具有相同的效果啦~感觉是可以使用了吧！
@ContextConfiguration("classpath:/example-context.xml")
@PrepareForTest(IdGenerator.class)

这个是解决的方案 
Java 7 introduced a stricter verification and changed the class format a bit – to contain a stack map, used to verify that code is correct. The exception you see, means that some method doesn’t have a valid stack map.

Java version or bytecode instrumentation could both be to blame. Usually this means that a library that the application uses, generates invalid bytecode that doesn’t pass the stricter verification. So nothing else than reporting it as a bug to the library can be done by the developer.

As a workaround you can add -noverify to the JVM arguments in order to disable verification. In Java 7 it was also possible to use -XX:-UseSplitVerifier to use the less strict verification method, but that option was removed in Java 8.

作为一种解决方法，你可以添加noverify的JVM参数来禁用验证。在java 7还可以使用XX：- usesplitverifier使用更严格的验证方法，但选择是在java 8中移除。

看起来还是顺利的解决啦问题，新的问题来啦，spring初始化的时候，引入的单例模式的初始化，加快加载的速度，报错啦，我们测试，没必要开启这么多的初始化的引入的工作。可以设置全局的禁止初始化。
