篇首语：最关情，折尽梅花，难寄相思。本文由小常识网(cha138.com)小编为大家整理，主要介绍了知识大全 ibatis+spring 集成相关的知识，希望对你有一定的参考价值。

　　作为开源的Orm对象映射框架 ibatis是一个线程安全学习容易但是开发相对于hibernate来说的话就要繁锁些没有很好的工具支持ibatis所有的配置几乎是通过手写这样增加了开发者的难度好啦言归正转下面编写实现

　　一引入spring ibatis jar包

　　二编写log j properties日志文件

　　log j rootLogger=DEBUG stdout

　　log j appender stdout= apache log j ConsoleAppender log j appender stdout layout= apache log j PatternLayout log j appender stdout layout ConversionPattern=%c % %m%n

　　log j logger java sql PreparedStatement=DEBUG

　　三建立Student java类映象属性

　　package terry ibatis pojo;

　　public class Student private Long id;

　　private String name;

　　private String subject;

　　private Long score;

　　public Long getId() return id;

　　public void setId(Long id) this id = id;

　　public String getName() return name;

　　public void setName(String name) this name = name;

　　public Long getScore() return score;

　　public void setScore(Long score) this score = score;

　　public String getSubject() return subject;

　　public void setSubject(String subject) this subject = subject;

　　四编写 student xml 映象文件

　　<?xml version= encoding= utf ?>

　　<!DOCTYPE sqlMap PUBLIC ////DTD sql Map //EN map dtd > <sqlMap namespace= student > <typeAlias alias= student type= terry ibatis pojo Student /> <resultMap class= student id= studentResult > <result property= id column= id jdbcType= number javaType= java lang Long /> <result property= name column= name /> <result property= subject column= subject /> <result property= score column= score /> </resultMap> <select id= selectAll resultMap= studentResult > select * from student </select> <select id= findbyId parameterClass= java lang Long resultClass= student > select * from student where id=#id# </select> <insert id= insert parameterClass= student > insert into student(id name subject score) values(#id# #name# #subject# #score#) </insert> <update id= update parameterClass= student > update student set name=#name# subject=#subject# score=#score# where id=#id# </update> <delete id= delete parameterClass= java lang Long > delete from student where id=#id# </delete> </sqlMap>

　　五编写 SqlMapConfig xml文件

　　<?xml version= encoding= utf ?>

　　<!DOCTYPE sqlMapConfig PUBLIC ////DTD sql Map Config //EN map config dtd > <sqlMapConfig> <sqlMap resource= /terry/ibatis/pojo/student xml /> </sqlMapConfig>

　　六编写 StudentDao java(实现类)

　　package terry ibatis dao;

　　import java io IOException; import java sql SQLException; import java util List;

　　import springframework beans factory xml XmlBeanFactory; import re io ClassPathResource; import re io Resource; import springframework orm ibatis SqlMapClientCallback; import springframework orm ibatis support SqlMapClientDaoSupport; import terry ibatis pojo Student;

　　import ibatis sqlmap client SqlMapExecutor;

　　public class StudentDao extends SqlMapClientDaoSupport implements Idao

　　public void delete(Long id) this getSqlMapClientTemplate() delete( delete id);

　　public Object findbyId(Long id) return this getSqlMapClientTemplate() queryForObject( findbyId id);

　　public List getAll() return (List)this getSqlMapClientTemplate() execute(new SqlMapClientCallback()

　　public Object doInSqlMapClient(SqlMapExecutor sqlMapper) throws SQLException return sqlMapper queryForList( selectAll ); );

　　public void save(Object o) this getSqlMapClientTemplate() insert( insert o);

　　public void update(Object o) this getSqlMapClientTemplate() update( update o); public static void main(String[] args) throws IOException Resource re=new ClassPathResource( Ibatis Context xml ); XmlBeanFactory xml=new XmlBeanFactory(re); StudentDao student=(StudentDao)xml getBean( studentDao ); Student stu=new Student(); stu setId(Long valueOf( )); stu setName( terry ); stu setScore(Long valueOf( )); stu setSubject( 数学 ); student delete(Long valueOf( ));

　　七配置 ApplicationContext xml文件

　　<?xml version= encoding= UTF ?> <!DOCTYPE beans PUBLIC //SPRING//DTD BEAN//EN beans dtd >
