Spring3.2 Contorller单元测试参数问题： java.lang.NoSuchMethodException

 使用3.2做单元测试的时候发现这个问题，因为之前都是用3.0中的配置适配器使用AnnotationMethodHandlerAdapter，到3.2中升级为RequestMappingHandlerAdapter；

运行之前的单元测试发现报异常：java.lang.NoSuchMethodException，看了一下堆栈发现反射调用的方法签名明显不对，于是看了一下调用的代码，

之前是：handlerAdapter.handle(request, response,  new HandlerMethod(controller, "setClassBreaksInfo"))

感觉是这里的问，继续看handle的参数，发现还有一个Class<?>... parameterTypes，预计根据这里还匹配调用参数签名的，于是改为跟调用方法签名对应的ClassType，然后可以正确运行了，整体配置如下：
