所需要用到的其他工具或技术:
项目管理工具 : Maven
测试运行工具 : Junit
数据库 : Derby
本节需要用到的有2部分，第一部分是如何在Derby中创建存储过程，第二部分是如何在Mybatis中调用存储过程
一. 在Derby中创建存储过程
在Eclipse中创建一个新的普通Java项目命名为Test_Store_Procedure
在com.bjpowernode.practice包下创建一个Class命名为StoreProcedureOperationClass.class
package com.bjpowernode.practice;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;
public class StoreProcedureOperationClass
{
public static void insertData(int id, String username, String password, String nickname) throws SQLException
{
Connection connection = DriverManager.getConnection("jdbc:default:connection");
PreparedStatement p =
connection.prepareStatement("INSERT INTO USER_TEST_TB(ID,USERNAME,PASSWORD,NICKNAME) VALUES(?,?,?,?)");
p.setInt(1, id);
p.setString(2, username);
p.setString(3, password);
p.setString(4, nickname);
System.out.println("INSERT VALUES (id=" + id + ",username=" + username + ",password=" + password + ",nickname="
+ nickname + ")");
p.executeUpdate();
p.close();
connection.close();
}
}
3. 利用jar命令或者Eclipse工具导出到C:freudTest_Store_Procedure.jar
4. 在ij命令行中声明存储过程
CREATE PROCEDURE FREUD.INSERT_USER(IN THE_ID INTEGER,
IN THE_USERNAME VARCHAr(20), IN THE_PASSWORD VARCHAr(20), IN THE_NICKNAME VARCHAr(20))
PARAMETER STYLE JAVA MODIFIES SQL DATA LANGUAGE JAVA
EXTERNAL NAME 'com.bjpowernode.practice.StoreProcedureOperationClass.insertData';
在 ij 控制台中调用call sqlj.install_jar('C:freudTest_Store_Procedure.jar', 'FREUD.TEST_SPROCEDURE', 0);将 jar 包导入到 FREUD模式中，并命名为TEST_SPROCEDURE。
6. 在 ij 控制台中调用call SYSCS_UTIL.SYSCS_SET_DATAbase_PROPERTY('derby.database.classpath', 'FREUD.TEST_SPROCEDURE'); 将 jar 包加入到数据库 classpath 搜索路径中。
这样，Derby的存储过程就算创建完成了
二.在Mybatis中调用存储过程
Maven Dependencies:org.mybatis mybatis3.2.7 junit junit4.9 test org.apache.derby derby10.10.2.0 org.apache.derby derbyclient10.10.2.0
Mybatis配置文件 src/main/resource源目录下
test-mybatis-configuration.xml
User.java对象类(src/main/java/com/freud/practice目录下)
package com.bjpowernode.practice;
public class User
{
private Integer id;
private String username;
private String password;
private String nickname;
public Integer getId()
{
return id;
}
public void setId(Integer id)
{
this.id = id;
}
public String getUsername()
{
return username;
}
public void setUsername(String username)
{
this.username = username;
}
public String getPassword()
{
return password;
}
public void setPassword(String password)
{
this.password = password;
}
public String getNickname()
{
return nickname;
}
public void setNickname(String nickname)
{
this.nickname = nickname;
}
}
UserMapper.xml Mapper文件（src/main/java/com.bjpowernode.practice目录下）
CALL FREUD.INSERT_USER(#{id},#{username},#{password},#{nickname})
UserMapper.java Mapper类（src/main/java/com.bjpowernode.practice目录下）
package com.bjpowernode.practice;
import java.util.List;
public interface UserMapper
{
public List getUser();
public void insertUser(User user);
}
测试类TestMyBatis.java（src/test/java/com.bjpowernode.practice目录下）
package com.bjpowernode.practice;
import java.io.InputStream;
import java.text.MessageFormat;
import java.util.List;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.Before;
import org.junit.Test;
public class TestMyBatis
{
private String source;
private InputStream inputStream;
private SqlSessionFactory sqlSessionFactory;
@Before
public void setUp()
{
source = "test-mybatis-configuration.xml";
inputStream = TestMyBatis.class.getClassLoader().getResourceAsStream(source);
sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
}
@Test
public void testInsert()
{
try
{
// 获取Session连接
SqlSession session = sqlSessionFactory.openSession();
// 获取Mapper
UserMapper userMapper = session.getMapper(UserMapper.class);
System.out.println("Test insert start...");
// 显示插入之前User信息
System.out.println("Before insert");
this.printUsers(userMapper.getUser());
// 执行插入
userMapper.insertUser(this.mockUser("FREU_INS_USER", "FREUD_INS_PASS", "FREUD_INS_NICK"));
// 提交事务
session.commit();
// 显示插入之后User信息
System.out.println("rnAfter insert");
this.printUsers(userMapper.getUser());
System.out.println("Test insert finished...");
}
catch (Exception e)
{
e.printStackTrace();
}
}
public User mockUser(String username, String password, String nickname)
{
User user = new User();
user.setId(50);
user.setUsername(username);
user.setPassword(password);
user.setNickname(nickname);
return user;
}
private void printUsers(final List users)
{
int count = 0;
for (User user : users)
{
System.out.println(MessageFormat.format("==User[{0}]=================", ++count));
System.out.println("User Id: " + user.getId());
System.out.println("User UserName: " + user.getUsername());
System.out.println("User Password: " + user.getPassword());
System.out.println("User nickname: " + user.getNickname());
}
}
}
