2.配置web.xml

  
    
        CharacterEncodingFilter
        org.springframework.web.filter.CharacterEncodingFilter
        
            encoding
            UTF-8
        
        
            forceResponseEncoding
            true
        
    
    
        CharacterEncodingFilter
        /*
    

    
    
        HiddenHttpMethodFilter
        org.springframework.web.filter.HiddenHttpMethodFilter
    
    
        HiddenHttpMethodFilter
        /*
    

    
    
        SpringMVC
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            classpath:springmvc.xml
        
        1
    
    
        SpringMVC
        /
    

    
    
        org.springframework.web.context.ContextLoaderListener
    


    
    
        contextConfigLocation
        classpath:spring.xml
    

3.配置自定义的springmvc.xml

• 拦截器和异常处理器可以根据需求配置

4.spring配置文件

spring整合mybatis

5. mybatis-config

未用spring整合的插件

6. 测试

只测试分页功能

 

6.1controller

@Controller
public class EmployeeController {

    @Autowired
    private EmployeeService employeeService;

    @RequestMapping(value = "/employee/page/{pageNum}",method = RequestMethod.GET)
    public String getEmployeePage(@PathVariable("pageNum") Integer pageNum,Model model) {
        //获取员工的分页信息
        PageInfo page=employeeService.getEmployeePage(pageNum);

        //将分页数据共享到请求域中
        model.addAttribute("page",page);

        return "employee";
    }
}

6.2Service

@Service
@Transactional
public class EmployeeServiceImpl implements EmployeeService {

    @Autowired
    private EmployeeMapper employeeMapper;


    @Override
    public PageInfo getEmployeePage(Integer pageNum) {
        //开启分页功能
        PageHelper.startPage(pageNum, 2);
        //查询所有员工信息
        List list= employeeMapper.getAllEmployee();

        //获取分页相关数据
        PageInfo page=new PageInfo<>(list,3);
        return page;
    }
}

6.3Dao

public interface EmployeeMapper {

    List getAllEmployee();
}
