JDK1.7 Spring4 在做controller单测时，mock静态方法试了好几种方式（mockUp和Expectations）都不行，报java.util.ServiceConfigurationError: com.sun.tools.attach.spi.AttachProvider: Provider sun.tools.attach.WindowsAttachProvider could not be instantiated这个错误，紧接着就是： java.lang.NullPointerException at mockit.internal.util.ClassLoad.loadByInternalName(ClassLoad.java:31) at mockit.internal.ClassLoadingBridge.setBridgeFields(ClassLoadingBridge.java:105) at mockit.internal.ClassLoadingBridge.getHostClassName(ClassLoadingBridge.java:96) at mockit.internal.BaseClassModifier.generateCodeToObtainInstanceOfClassLoadingBridge(BaseClassModifier.java:171) at mockit.internal.faking.FakedClassModifier.generateCallToFakeMethodThroughClassLoadingBridge(FakedClassModifier.java:250) at mockit.internal.faking.FakedClassModifier.generateCallToFakeMethod(FakedClassModifier.java:239) at mockit.internal.faking.FakedClassModifier.generateConditionalCallForFakedMethod(FakedClassModifier.java:211) at mockit.internal.faking.FakedClassModifier.generateDynamicCallToFake(FakedClassModifier.java:166) at mockit.internal.faking.FakedClassModifier.visitMethod(FakedClassModifier.java:118) at mockit.external.asm.ClassReader.readMethod(ClassReader.java:770) at mockit.external.asm.ClassReader.readFieldsAndMethods(ClassReader.java:596) at mockit.external.asm.ClassReader.accept(ClassReader.java:503) at mockit.internal.faking.FakeClassSetup.modifyRealClass(FakeClassSetup.java:97) at mockit.internal.faking.FakeClassSetup.redefineMethods(FakeClassSetup.java:77) at mockit.MockUp.redefineMethods(MockUp.java:197) at mockit.MockUp.redefineClassOrImplementInterface(MockUp.java:182) at mockit.MockUp.<init>(MockUp.java:129) at cn.px.dxs.web.controller.h5.AbnormalControllerTest$1.<init>(AbnormalControllerTest.java:86) at cn.px.dxs.web.controller.h5.AbnormalControllerTest.getPosVersionAll(AbnormalControllerTest.java:86) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:26) at org.springframework.test.context.junit4.statements.RunBeforeTestMethodCallbacks.evaluate(RunBeforeTestMethodCallbacks.java:73) at org.springframework.test.context.junit4.statements.RunAfterTestMethodCallbacks.evaluate(RunAfterTestMethodCallbacks.java:82) at org.springframework.test.context.junit4.statements.SpringRepeat.evaluate(SpringRepeat.java:73) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:224) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:83) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:68) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:163) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:68) at com.intellij.rt.execution.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:47) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:242) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70)

写法如下： ` new MockUp(){ @Mock public Map<Long, Restaurant> getHotelInfoCache(HttpServletRequest request){ Map<Long, Restaurant> map = new HashMap<>(); map.put(300000094l,new Restaurant()); return map; } };

    /*new Expectations(WebUtil.class){
        {
            WebUtil.getHotelInfoCache((HttpServletRequest) any);
            Map<Long, Restaurant> map = new HashMap<>();
            map.put(300000094l,new Restaurant());
            result = map;
        }
    };*/

` 求大神赐教。

jmockit包引在Junit下面了，调整一下俩包的顺序好了
