对于整合问题解决办法：
异常截图：

错误原因：
根据里面提示是注入没有成功，但是我用注解和xml文件配置以及java配置都没有用。这时我就在想是不是根本就没有找spring-*.xml文件。web.xml配置果然出了问题：
<!-- 配置前端控制器-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
写成了
<listener>
<listener-class>org.springframework.web.context.ContextCleanupListener</listener-class>
</listener>
这一来还暴露了一些问题，自己太过于依赖开发工具，英语认真过关啊。
网上我也整理了一下解决方法：

设置dispatcherServlet初始化参数的时候检查 contextConfigLocation等一些文件配置路径问题。

这种非法参数，是因为版本问题，jdk和spring版本匹配问题
（只是示例，并不一定非要这样设置，总之需要同时匹配这四项）
使用JavaSE1.7+spring3.2.0+facetJava1.7+tomcat7。
使用JavaSE1.8+spring4.1.6+facetJava1.8+tomcat8。
然而我是nobeansuchException异常~~~
这种是还是因为web.xml里面，
当然这一切还是因为我使用了阶段性检查：
我首先对mapper层进行测试：
测试类如下：
package com.pesystem.mapper;
import com.pesystem.po.Faculty;
import com.pesystem.po.FacultyExample;
import org.apache.log4j.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:springConfig/spring-dao.xml"})
public class FacultyMapperTest {
//获取日志记录器Logger，名字为本类类名
private static Logger log = Logger.getLogger(String.valueOf(FacultyMapperTest.class));
@Autowired
private FacultyMapper facultyMapper;
@Test
public void testInsert(){
Faculty faculty = new Faculty();
faculty.setFacultyName("BarkLuc，不得转载。。。。");
facultyMapper.insert(faculty);
}
}
这里还出现了一个小插曲，它很多次出现非法参数异常。原来是springframework test包，和spring其他核心包版本不一致导致的。~~。一看源码原来是项目生成的时候，没有把配置处理干净。

错误原因：springframework的test和核心版本不一致导致的。
修改依赖，同为4.3.8就对了。
测试就报错，异常代码如下：

所以以前对的东西现在不一定对~~~，不用就要删除掉。
更改以后成功通过。
对于serivce层进行测试
package com.pesystem.service;
import com.pesystem.mapper.FacultyMapper;
import com.pesystem.po.Faculty;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:springConfig/spring-service.xml","classpath:springConfig/spring-dao.xml"})
public class FacultyServiceTest {
@Autowired
private FacultyService facultyService;
@Test
public void testInsert(){
facultyService.testSelectOne();
}
}
在这测试的时候，我尝试使用通配符貌似是无法通过的~~
经过测试，是没有问题的。
controller层也是有相应的测试方法：但是根据书上的我只能推断出部分测试方法，但因为无法自动注入我确实没了脾气，以后会更新测试方法：
package com.pesystem.controller;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.stereotype.Controller;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.web.servlet.MockMvc;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.view;
import static org.springframework.test.web.servlet.setup.MockMvcBuilders.standaloneSetup;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:springConfig/spring-dao.xml",
"classpath:springConfig/spring-service.xml",
"classpath:springConfig/spring-transition.xml",
"classpath:springConfig/springmvc.xml"})
public class FacultyServiceTest {
@Test
public void testSelectOne() throws Exception {
FacultyController facultyController = new FacultyController();
MockMvc build = standaloneSetup(facultyController).build();
build.perform(get("/faculty/selectFaculties.action")).andExpect(view().name("faculty"));
}
}
