8.MBG的运行代码

public class MBGTest {
     
    @Test
    public void test() throws Exception {
     
        List<String> warnings = new ArrayList<String>();
        boolean overwrite = true;
        File configFile = new File("MBG.xml");
        ConfigurationParser cp = new ConfigurationParser(warnings);
        Configuration config = cp.parseConfiguration(configFile);
        DefaultShellCallback callback = new DefaultShellCallback(overwrite);
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
        myBatisGenerator.generate(null);
    }
}

9.Spring单元测试(模拟请求)

@WebAppConfiguration    //@Autowired只能获取ioc容器里面的  需要获取ioc容器就要加@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
     "classpath:application.xml","classpath:SpringMVC.xml"})
public class PageInfoTest {
     
    @Autowired   //加入SpringMvc的ioc
    WebApplicationContext webApplicationContext;
    MockMvc mockMvc;   //虚拟请求
    @Before
    public void initMockMvc(){
     
        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }
    @Test
    public void test() throws Exception {
     
        MvcResult result = mockMvc.perform(MockMvcRequestBuilders.get("/emps").param("pa", "5")).andReturn();
        PageInfo page = (PageInfo) result.getRequest().getAttribute("pageInfo");
        System.out.println("第" + page.getPageNum() + "页");
        System.out.println("共" + page.getPages() + "页");
        int[] nums = page.getNavigatepageNums();
        System.out.println(Arrays.toString(nums));
        List<Employee> pageList = page.getList();
        for (Employee employee : pageList){
     
            System.out.println(employee);
        }
    }

}
