Mybatis中如何调用存储过程

下面就用一个例子来测试Mybatis调用存储过程，并进行分页的例子:

使用的是oracle数据库

1 存储过程代码如下：

create or replace procedure test_page(
    page_start in int,page_end in int,page_count out int,
    page_emps out sys_refcursor)
as
begin
    select count(*) into page_count from employees;    
    open page_emps for
        select * from 
               (select rownum rn,e.* from employees e
                 where rownum <= page_end)
        where rn >= page_start;
end test_page;      

2 Page.java

package com.lxj.bean;

import java.util.List;

public class Page {
	// 起始
	private Integer start;
	// 结束
	private Integer end;
	// 总数
	private Integer count;
	// 数据库中查询出来的员工
	private List emps;

	public Integer getStart() {
		return start;
	}

	public void setStart(Integer start) {
		this.start = start;
	}

	public Integer getEnd() {
		return end;
	}

	public void setEnd(Integer end) {
		this.end = end;
	}

	public Integer getCount() {
		return count;
	}

	public void setCount(Integer count) {
		this.count = count;
	}

	public List getEmps() {
		return emps;
	}

	public void setEmps(List emps) {
		this.emps = emps;
	}

	@Override
	public String toString() {
		return "Page [start=" + start + ", end=" + end + ", count=" + count + ", emps=" + emps + "]";
	}

}

3 Employee.java

package com.lxj.bean;

public class Employee {

	private Integer id;
	private String lastName;
	private String email;
	private String gender;

	public Integer getId() {
		return id;
	}

	public void setId(Integer id) {
		this.id = id;
	}

	public String getLastName() {
		return lastName;
	}

	public void setLastName(String lastName) {
		this.lastName = lastName;
	}

	public String getEmail() {
		return email;
	}

	public void setEmail(String email) {
		this.email = email;
	}

	public String getGender() {
		return gender;
	}

	public void setGender(String gender) {
		this.gender = gender;
	}

	@Override
	public String toString() {
		return "Employee [id=" + id + ", lastName=" + lastName + ", email=" + email + ", gender=" + gender + "]";
	}

}

4 EmployeeMapper.java

package com.lxj.mapper;

import java.util.List;

import com.lxj.bean.Employee;
import com.lxj.bean.Page;

public interface EmployeeMapper {
	
	  //根据Id获取员工信息
	  public Employee getEmpById(Integer id);
	  
	  //分页获取员工信息
	  public void getEmpsByPage(Page page);
	  
}

5 EmployeeMapper.xml

 
	
		select EMPLOYEE_ID id,LAST_NAME lastName,EMAIL email from employees 
        where EMPLOYEE_ID = #{id}
	
	
	
	
	    {call test_page(
	        #{start,mode=IN,jdbcType=INTEGER},
	        #{end,mode=IN,jdbcType=INTEGER},
	        #{count,mode=OUT,jdbcType=INTEGER},
	        #{emps,mode=OUT,jdbcType=CURSOR,javaType=ResultSet,resultMap=TestPge}
	    )}
	
	
	   
	   
	   
	

6 测试

查看一下数据库：

取出的是从15-20，共6条记录，总记录数是20，没有任何问题
