你需要的Mybatis調用Oracle存儲過程

1. DAO接口

public interface EmpDao {
    void addEmp1();

    void findEmp(Map<String,Object> map);

    void findEmpById(Map<String,Object> map);
    
    void findEmpBySalary(Map<String,Object> map);
}

2.無參數無返回值存儲過程調用

<update id="addEmp1" statementType="CALLABLE">
        {CALL addEmp_pro()}
</update>

測試略

3.無參數返回值爲遊標類型

mapper文件

<mapper namespace="com.baizhi.mybatis.EmpDao">
    <resultMap id="FINDEMP_MAP" type="com.baizhi.bean.Emp">
        <id property="id" column="id"></id>
        <result property="name" column="name"></result>
        <result property="salary" column="salary"></result>
    </resultMap>
    <update id="findEmp" statementType="CALLABLE">
        {CALL findAllEmp_pro(#{cur_emp,mode=OUT,jdbcType=CURSOR,javaType=ResultSet,resultMap=FINDEMP_MAP})}
    </update>
</mapper>

測試類

    @Test
    public void test1() throws Exception {
        SqlSession sqlSession = openSqlSession();
        EmpDao dao = sqlSession.getMapper(EmpDao.class);
        Map<String, Object> map = new HashMap<>();
        map.put("cur_emp", OracleTypes.CURSOR);
        dao.findEmp(map);
        List<Emp> app = (List<Emp>) map.get("cur_emp");
        for (Emp emp : app) {
            System.out.println(emp);
        }
    }

4.有參數有返回值

mapper文件

    <update id="findEmpById" statementType="CALLABLE">
        {CALL findEmpById_pro(#{eid,mode=INOUT,jdbcType=INTEGER},
                              #{ename,mode=OUT,jdbcType=VARCHAR},
                              #{esalary,mode=OUT,jdbcType=DOUBLE})}
    </update>

測試調用

    @Test
    public void test3() throws Exception {
        SqlSession sqlSession = openSqlSession();
        EmpDao dao = sqlSession.getMapper(EmpDao.class);
        Map<String, Object> map = new HashMap<>();
        map.put("eid", 100);
        dao.findEmpById(map);

        System.out.println(map);
    }

5.有參數返回值爲遊標類型

mapper文件

 <update id="findEmpBySalary" statementType="CALLABLE">
        {CALL findEmpBySalary_pro(#{esalary,mode=IN,jdbcType=DOUBLE},
                              #{cur_emp,mode=OUT,jdbcType=CURSOR,javaType=ResultSet,resultMap=FINDEMP_MAP})}
    </update>

測試調用

    @Test
    public void test4() throws Exception {
        SqlSession sqlSession = openSqlSession();
        EmpDao dao = sqlSession.getMapper(EmpDao.class);
        Map<String, Object> map = new HashMap<>();
        map.put("esalary", 10000);
        dao.findEmpBySalary(map);

        System.out.println(map);

        //獲取到emp的結果集合
        List<Emp> emps = (List<Emp>) map.get("cur_emp");
        for (Emp emp : emps) {
            System.out.println(emp);
        }
    }

附測試數據和存儲過程

--存儲過程1
create or replace procedure addEmp_pro 
as 
begin
	insert into emp values(emp_seq.nextval,'Tom',1000);
	commit;
end;

--存儲過程2
create or replace procedure findAllEmp_pro( cur_emp OUT sys_refcursor)
	as
begin
	open cur_emp for select * from emp;
end;

--存儲過程3
create or replace procedure findEmpById_pro(eid in out number,ename out varchar2,esalary out number)
  as
begin
  select * into eid,ename,esalary from emp where id=eid;
end;

--存儲過程4
create or replace procedure findEmpBySalary_pro(esalary number,cur_emp OUT sys_refcursor)
  as
begin
  open cur_emp for select * from emp where salary=esalary;
end;

drop table emp;

create table emp(
id number(9) primary key,
name varchar2(50),
salary number(9,3)
);


insert into emp select employee_id,first_name,salary from employees;

commit;

select * from emp;
