注意注意！！！
配置上面之后，应该可以使用了，但是必须注意下面一些问题

注意问题

在配置文件中，一些部分使用了我的包名，所以你必须修改为你的，也就是你必须建立对应的包，否则报错
目录问题，其实要注意的目录应该也就是mybatis中mapper文件，mapper文件以及对应的mapper配置文件，说简单的一个接口文件一个是写sql的配置文件，这俩务必在一个目录下面，如果不一样，使用这个方法可以有效的解决property name="mapperLocations" value="classpath:mapper/*.xml，在spring里面加在带有org.mybatis.spring.SqlSessionFactoryBean这个bean标签里面

把上面的问题解决了，我相信项目可以正常跑起来了。

下面是一个测试项目，但是必须完成上面操作之后

EmployeeController

@Controller
public class EmployeeController {

    @Autowired
    private EmployeeService employeeService;

    @RequestMapping(value = "/employee", method = RequestMethod.GET)
    public String getAllEmployeeList(Model model){
        List<Employee> list = employeeService.getEmployeeList();
        model.addAttribute("list", list);
        return "employee_list";
    }

    @RequestMapping(value = "/employee/page/{pageNum}", method = RequestMethod.GET)
    public String getEmployeePage(Model model, @PathVariable("pageNum") Integer pageNum){
        PageInfo<Employee> page = employeeService.getEmployeePage(pageNum);
        model.addAttribute("page", page);
        return "employee_list_page";
    }

    @RequestMapping(value = "/employee/{delteid}")
    public String getEmployeePage(Model model, @PathVariable("delteid") int delteid){
        employeeService.getDeleteid(delteid);

        System.out.println("删除的id为"+delteid);
        return "success";
    }
}

Employee

public class Employee {
    private Integer empId;
    private String empName;
    private Integer age;

    @Override
    public String toString() {
        return "Employee{" +
                "empId=" + empId +
                ", empName='" + empName + '\'' +
                ", age=" + age +
                '}';
    }

    public Integer getEmpId() {
        return empId;
    }

    public void setEmpId(Integer empId) {
        this.empId = empId;
    }

    public String getEmpName() {
        return empName;
    }

    public void setEmpName(String empName) {
        this.empName = empName;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }


    public Employee(Integer empId, String empName, Integer age) {
        this.empId = empId;
        this.empName = empName;
        this.age = age;

    }
    public Employee() {
    }
}

EmployeeService接口

public interface EmployeeService {
    List<Employee> getEmployeeList();

    PageInfo<Employee> getEmployeePage(Integer pageNum);

    void getDeleteid(int id);
}

EmployeeService实现类

@Service
@Transactional
public class EmployeeServiceImpl implements EmployeeService {

    @Autowired
    private EmployeeMapper employeeMapper;

    @Override
    public List<Employee> getEmployeeList() {
        return employeeMapper.getEmployeeList();
    }

    @Override
    public PageInfo<Employee> getEmployeePage(Integer pageNum) {
        PageHelper.startPage(pageNum, 4);
        List<Employee> list = employeeMapper.getEmployeeList();
        PageInfo<Employee> page = new PageInfo<>(list, 5);
        return page;
    }

    @Override
    public void getDeleteid(int id) {
        employeeMapper.deleteByid(id);
    }
}

mapper文件

public interface EmployeeMapper {

    List<Employee> getEmployeeList();

    void deleteByid(int id);
}

注意！！！
实现这个小案例
必须要有数据库，自己想测试自己测试下，建立一个简单的表，站长当时测试的时候也是自己建立的数据，随便弄了一个数据库表，这都不重要，重要就是体会下，ssm整合之后怎么去使用，数据库我就不放出来了，自己搞下简单

整合ssm框架使用方法
