Mybatis基础操作之存储过程
mybatis调用存储过程非常的方便，下面开始学习Mybatis/Ibatis 2如何调用Oracle的存储过程。先学习一个简单输出文本的例子：
Java代码
<SPAN>CREATE OR REPLACE PROCEDURE proc_out(yes IN VARCHAR2,fly OUT VARCHAR2) AS
begin
dbms_output.put_line(yes);
fly:='return something';
end proc_out;
</SPAN>
<span>CREATE OR REPLACE PROCEDURE proc_out(yes IN VARCHAR2,fly OUT VARCHAR2) AS begin dbms_output.put_line(yes); fly:='return something'; end proc_out; </span>
Mybatis调用配置如下：
Java代码
<SPAN><select id="testOutput" statementType="CALLABLE" parameterType="hashmap">
<![CDATA[ {call proc_out(#{yes, mode=IN, jdbcType=VARCHAR}, #{gog, mode=OUT, jdbcType=VARCHAR})}]]>
</select></SPAN>
<span><select id="testOutput" statementType="CALLABLE" parameterType="hashmap">
<![CDATA[ {call proc_out(#{yes, mode=IN, jdbcType=VARCHAR}, #{gog, mode=OUT, jdbcType=VARCHAR})}]]>
</select></span>测试方法如下：
Java代码
<SPAN>public void TestOutputCallable(SqlSessionFactory ssf2) {
SqlSession sqlSession = ssf2.openSession();
Map params = new HashMap();
// 调用存储过程的传递的参数名可以不和定义存储过程的参数名保持一致，只要保证它们的顺序是一致的即可。
params.put("yes", "china");
sqlSession.selectOne("test.testOutput", params);
String result = (String) params.get("gog");
System.out.println(result);
}</SPAN>
<span>public void TestOutputCallable(SqlSessionFactory ssf2) {
SqlSession sqlSession = ssf2.openSession();
Map params = new HashMap();
// 调用存储过程的传递的参数名可以不和定义存储过程的参数名保持一致，只要保证它们的顺序是一致的即可。
params.put("yes", "china");
sqlSession.selectOne("test.testOutput", params);
String result = (String) params.get("gog");
System.out.println(result);
}</span>Ibatis配置如下：
Java代码
<SPAN><parameterMap id="stringOutMap" class="java.util.Map">
<!-- mode参数用来设置是传入参数还是返回参数 -->
<parameter property="yes" javaType="String" jdbcType="VARCHAR"
mode="IN" />
<parameter property="fly" javaType="String" jdbcType="VARCHAR"
mode="OUT" />
</parameterMap>
<procedure id="testOutput" parameterMap="stringOutMap">
<![CDATA[{call proc_out(?,?)}]]>
</procedure></SPAN>
<span><parameterMap id="stringOutMap" class="java.util.Map">
<!-- mode参数用来设置是传入参数还是返回参数 -->
<parameter property="yes" javaType="String" jdbcType="VARCHAR"
mode="IN" />
<parameter property="fly" javaType="String" jdbcType="VARCHAR"
mode="OUT" />
</parameterMap>
<procedure id="testOutput" parameterMap="stringOutMap">
<![CDATA[{call proc_out(?,?)}]]>
</procedure></span>测试方法为：
Java代码
<SPAN>public void TestOutputCallable(SqlMapClient sqlMapper) throws SQLException {
Map mapIn = new HashMap();
mapIn.put("yes", "china");
mapIn.put("fly", "");
sqlMapper.queryForObject("test.testOutput",mapIn);
String result=(String) mapIn.get("fly");
System.out.println(result);
}</SPAN>
<span>public void TestOutputCallable(SqlMapClient sqlMapper) throws SQLException {
Map mapIn = new HashMap();
mapIn.put("yes", "china");
mapIn.put("fly", "");
sqlMapper.queryForObject("test.testOutput",mapIn);
String result=(String) mapIn.get("fly");
System.out.println(result);
}</span>Ps，Ibatis每次输入都要新建一个Map来指定输入参数和输出参数，用起来特不爽，还是Mybatis好用
下面开始使用表了， 首先新建表Emp：
Java代码
<SPAN>-- Create table
create table EMP
(
EMPNO NUMBER not null,
ENAME VARCHAR2(30) not null,
JOB VARCHAR2(15),
MGR NUMBER,
HIREDATE DATE,
SALE NUMBER,
COMM NUMBER,
DEPTNO NUMBER
)
-- Create/Recreate primary, unique and foreign key constraints
alter table EMP
add primary key (EMPNO)
</SPAN>
<span>-- Create table create table EMP ( EMPNO NUMBER not null, ENAME VARCHAR2(30) not null, JOB VARCHAR2(15), MGR NUMBER, HIREDATE DATE, SALE NUMBER, COMM NUMBER, DEPTNO NUMBER ) -- Create/Recreate primary, unique and foreign key constraints alter table EMP add primary key (EMPNO) </span>
再新建JavaBean
Java代码
<SPAN>package bean;
import java.util.Date;
public class EmpBean {
@Override
public String toString() {
return "EmpBean [empNo=" + empNo + ", ename=" + ename + ", job=" + job
+ ", mrg=" + mrg + ", hireDate=" + hireDate.toLocaleString()
+ ", sale=" + sale + ", comm=" + comm + ", depNo=" + depNo
+ "]";
}
private long empNo;
private String ename;
private String job;
private long mrg;
private Date hireDate;
private long sale;
private long comm=0;
private long depNo;
public long getEmpNo() {
return empNo;
}
public void setEmpNo(long empNo) {
this.empNo = empNo;
}
public String getEname() {
return ename;
}
public void setEname(String ename) {
this.ename = ename;
}
public String getJob() {
return job;
}
public void setJob(String job) {
this.job = job;
}
public long getMrg() {
return mrg;
}
public void setMrg(long mrg) {
this.mrg = mrg;
}
public Date getHireDate() {
return hireDate;
}
public void setHireDate(Date hireDate) {
this.hireDate = hireDate;
}
public long getSale() {
return sale;
}
public void setSale(long sale) {
this.sale = sale;
}
public long getComm() {
return comm;
}
public void setComm(long comm) {
this.comm = comm;
}
public long getDepNo() {
return depNo;
}
public void setDepNo(long depNo) {
this.depNo = depNo;
}
}
</SPAN>
<span>package bean;
import java.util.Date;
public class EmpBean {
@Override
public String toString() {
return "EmpBean [empNo=" + empNo + ", ename=" + ename + ", job=" + job
+ ", mrg=" + mrg + ", hireDate=" + hireDate.toLocaleString()
+ ", sale=" + sale + ", comm=" + comm + ", depNo=" + depNo
+ "]";
}
private long empNo;
private String ename;
private String job;
private long mrg;
private Date hireDate;
private
193a0
long sale;
private long comm=0;
private long depNo;
public long getEmpNo() {
return empNo;
}
public void setEmpNo(long empNo) {
this.empNo = empNo;
}
public String getEname() {
return ename;
}
public void setEname(String ename) {
this.ename = ename;
}
public String getJob() {
return job;
}
public void setJob(String job) {
this.job = job;
}
public long getMrg() {
return mrg;
}
public void setMrg(long mrg) {
this.mrg = mrg;
}
public Date getHireDate() {
return hireDate;
}
public void setHireDate(Date hireDate) {
this.hireDate = hireDate;
}
public long getSale() {
return sale;
}
public void setSale(long sale) {
this.sale = sale;
}
public long getComm() {
return comm;
}
public void setComm(long comm) {
this.comm = comm;
}
public long getDepNo() {
return depNo;
}
public void setDepNo(long depNo) {
this.depNo = depNo;
}
}
</span>先来一个根据主键得到Emp记录的例子，对应的存储过程为：
Java代码
<SPAN>create or replace procedure getEmpById(V_USERID IN NUMBER,
V_CURSOR OUT SYS_REFCURSOR) is
begin
OPEN V_CURSOR FOR
SELECT * from emp WHERE empno = V_USERID;
end getEmpById;
</SPAN>
<span>create or replace procedure getEmpById(V_USERID IN NUMBER, V_CURSOR OUT SYS_REFCURSOR) is begin OPEN V_CURSOR FOR SELECT * from emp WHERE empno = V_USERID; end getEmpById; </span>
Mybatis配置如下：
Java代码
<SPAN><resultMap id="enameMap" type="bean.EmpBean">
<result column="EMPNO" property="empNo" />
<result column="ENAME" property="ename" />
<result column="JOB" property="job" />

<result column="HIREDATE" property="hireDate" />
<result column="SALE" property="sale" />
<result column="COMM" property="comm" />
<result column="DEPTNO" property="depNo" />

</update></SPAN>
<span><resultMap id="enameMap" type="bean.EmpBean">

</resultMap>
<update id="selectEmpById" statementType="CALLABLE"

</update></span>测试方法为：
Java代码
<SPAN>public void TestGetEmpByIdCallable(SqlSessionFactory ssf2) {
SqlSession sqlSession = ssf2.openSession();
Map params = new HashMap();
// 调用存储过程的传递的参数名可以不和定义存储过程的参数名保持一致，只要保证它们的顺序是一致的即可。
params.put("userid", 7769);
sqlSession.selectOne("test.selectEmpById", params);
List<EmpBean> list = (List<EmpBean>) params.get("emp");
System.out.println(list.size() + "---" + list.get(0).toString());
}</SPAN>
<span>public void TestGetEmpByIdCallable(SqlSessionFactory ssf2) {

sqlSession.selectOne("test.selectEmpById", params);
List<EmpBean> list = (List<EmpBean>) params.get("emp");
System.out.println(list.size() + "---" + list.get(0).toString());
}</span>Ibatis配置为：
Java代码
<SPAN><parameterMap id="empListParam" class="java.util.Map">
<parameter property="userid" javaType="Long" jdbcType="NUMBER"

List<EmpBean> list = sqlMapper.queryForList("test.selectEmpById",t);
System.out.println(list.size()+"----="+list.get(0).toString());
}</span>下面学习使用存储过程进行普通的增删改查操作，首先是新增，新建存储过程
Java代码
<SPAN>create or replace procedure addEmp(e_no in long,
e_name in varchar2,
e_job in varchar2,
e_mgr in long,
e_date in date,

message := '插入用户表成功';
commit;
EXCEPTION

end addEmp;
</SPAN>
<span>create or replace procedure addEmp(e_no in long, e_name in varchar2, e_job in varchar2, e_mgr in long, e_date in date, e_sale in long, e_comm in long, e_depno in long, message out varchar2) is begin insert into emp (EMPNO, ENAME, JOB, MGR, HIREDATE, SALE, COMM, DEPTNO) VALUES (e_no, e_name, e_job, e_mgr, e_date, e_sale, e_comm, e_depno); message := '插入用户表成功'; commit; EXCEPTION WHEN OTHERS THEN message := '插入用户表失败'; end addEmp; </span>

System.out.println(result);
}</SPAN>
<span>public void TestDelEmpCallable(SqlSessionFactory ssf2) {
SqlSession sqlSession = ssf2.openSession();
Map params = new HashMap();
params.put("id", 7844);
sqlSession.selectOne("test.delEmp", params);
String result = (String) params.get("message");
System.out.println(result);
}</span>Ibatis配置为：
Java代码
<SPAN><parameterMap id="delEmpMap" class="java.util.Map">
<parameter property="empNo" jdbcType="NUMBER" javaType="java.lang.Long"
mode="IN" />
<parameter property="message" jdbcType="VARCHAR" javaType="java.lang.String"
mode="OUT" />
</parameterMap>
<procedure id="delEmp" parameterMap="delEmpMap">
<![CDATA[{call delEmp(?,?)}]]>
</procedure></SPAN>
<span><parameterMap id="delEmpMap" class="java.util.Map">
<parameter property="empNo" jdbcType="NUMBER" javaType="java.lang.Long"
mode="IN" />
<parameter property="message" jdbcType="VARCHAR" javaType="java.lang.String"
mode="OUT" />
</parameterMap>
<procedure id="delEmp" parameterMap="delEmpMap">
<![CDATA[{call delEmp(?,?)}]]>
</procedure></span>对应的测试方法为：
Java代码
<SPAN>public void delEmpCallable(SqlMapClient sqlMapper)throws SQLException{
Map params = new HashMap();
params.put("empNo", 124L);
params.put("message","");
sqlMapper.update("test.delEmp",params);
System.out.println(params.get("message"));
}</SPAN>
<span>public void delEmpCallable(SqlMapClient sqlMapper)throws SQLException{
Map params = new HashMap();
params.put("empNo", 124L);
params.put("message","");
sqlMapper.update("test.delEmp",params);
System.out.println(params.get("message"));
}</span>全文完。
题外话：
在测试的过程中，发现Mybatis在Number类型记录不存在时候自动返回0，Ibatis直接报错，不知道是不是Ibatis配置出错了，另外，个人感觉Ibatis调用存储过程应该有更简洁的方法，欢迎各位指教，写的不好的地方，请多包涵，另外，本文中的例子网上也要，个人只是把他们整合在一起。
