如何mock java类中的static方法

在类名上加上如下标签

@RunWith(PowerMockRunner.class)
@PrepareForTest(Util.class)
@PowerMockIgnore({"javax.management.*", "javax.script.*"})

类似如下图这种

Object[] object = new Object[]{"11",contextProvider};
PowerMockito.mockStatic(Util.class);
when(Util.getInputParameters(Mockito.any(), Mockito.any(), Mockito.any())).thenAnswer((Answer<Object[]>) invocation -> object);
Object testResult = Util.getInputParameters(method, "", contextProvider);

最后会发现函数返回和预期是一致的
Assert.assertEquals(testResult, object);
