ibatis结合Struts2.0, Spring实现增，删，改，查的基本功能
ibatis结合Struts2.0, Spring实现增，删，改，查的基本功能
1.JavaBean:Person.java
package com.baoz.ibatis.entity;
import java.util.Date;
public class Person {
private Integer id;
private String firstName;
private String lastName;
private Date birthDate;
private Double weight;
private Double height;
public Date getBirthDate() {
return birthDate;
}
public void setBirthDate(Date birthDate) {
this.birthDate = birthDate;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public double getHeight() {
return height;
}
public void setHeight(double height) {
this.height = height;
}
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 Double getWeight() {
return weight;
}
public void setWeight(Double weight) {
this.weight = weight;
}
public void setHeight(Double height) {
this.height = height;
}
}
2.ibatis映射配置：
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-2.dtd" > <sqlMap namespace="person"> <typeAlias alias="Person" type="com.baoz.ibatis.entity.Person"/> <select id="readForId" resultClass="Person" parameterClass="java.lang.Integer"> select * from person where id=#value# </select> <select id="queryList" resultClass="Person"> select * from person </select> <insert id="add" parameterClass="Person" > insert into person (firstName, lastName, birthDate, weight, height) values(#firstName#, #lastName#, #birthDate#, #weight#, #height#) </insert> <update id="update" parameterClass="Person"> update person set firstName=#firstName#, lastName=#lastName#, birthDate=#birthDate#, weight=#weight#, height=#height# where id=#id# </update> <delete id="delete" parameterClass="java.lang.Integer"> delete from person where id=#value# </delete> </sqlMap>
3.ibatis配置实例
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE sqlMapConfig PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-config-2.dtd"> <sqlMapConfig> <settings useStatementNamespaces="true"/> <sqlMap resource="com/baoz/ibatis/xmls/person.xml"/> </sqlMapConfig>
4.struts2.0的配置文件：
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true" />
<constant name="struts.i18n.encoding" value="UTF-8" />
<include file="struts-default.xml"></include>
<package name="myAction" extends="struts-default">
<action name="person" class="com.baoz.ibatis.action.PersonAction">
<result name="list">/personList.jsp</result>
<result name="add">/personEdit.jsp</result>
</action>
</package>
</struts>
5.spring的配置文件
<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"> <context:annotation-config /> <context:component-scan base-package="com.baoz" /> <bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" /> <bean id="myDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"> </property> <property name="url" value="jdbc:mysql://127.0.0.1:3306/ibatisDB"> </property> <property name="username" value="root"></property> <property name="password" value="root"></property> </bean> <bean id="myIbatis" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean"> <property name="configLocation" value="sqlMapConfigExample.xml"> </property> <property name="dataSource" ref="myDataSource"></property> </bean> <bean id="personDao" class="com.baoz.ibatis.dao.PersonDao"> <property name="sqlMapClient" ref="myIbatis"></property> </bean> <bean id="personService" name="personService" class="com.baoz.ibatis.service.PersonService" scope="singleton"> </bean> </beans>
6.怎样用ibatis的dao：
package com.baoz.ibatis.dao;
import java.util.List;
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
import com.baoz.ibatis.entity.Person;
public class PersonDao extends SqlMapClientDaoSupport {
public Person readForId(int id){
return (Person)getSqlMapClientTemplate().queryForObject("person.readForId", id);
}
public List queryList(){
return getSqlMapClientTemplate().queryForList("person.queryList");
}
public void add(Person person){
getSqlMapClientTemplate().insert("person.add", person);
}
public void update(Person person){
getSqlMapClientTemplate().update("person.update", person);
}
public void delete(int id){
getSqlMapClientTemplate().delete("person.delete", id);
}
}
7.Service:
package com.baoz.ibatis.IService;
import java.util.List;
import com.baoz.ibatis.entity.Person;
public interface IPersonService {
public void insert(Person person);
public List queryList();
public Person readForid(int id);
public void update(Person person);
public void delete(int id);
}
package com.baoz.ibatis.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import com.baoz.ibatis.IService.IPersonService;
import com.baoz.ibatis.dao.PersonDao;
import com.baoz.ibatis.entity.Person;
public class PersonService implements IPersonService {
@Autowired
@Qualifier("personDao")
private PersonDao personDao;
public Person readForid(int id){
return personDao.readForId(id);
}
public void insert(Person person){
personDao.add(person);
}
public void add(Person person){
personDao.add(person);
}
public void update(Person person){
personDao.update(person);
}
public void delete(int id){
personDao.delete(id);
}
public PersonDao getPersonDao() {
return personDao;
}
public void setPersonDao(PersonDao personDao) {
this.personDao = personDao;
}
public List queryList() {
return personDao.queryList();
}
}
8.Action:
package com.baoz.ibatis.action;
import java.util.List;
import org.apache.commons.beanutils.MethodUtils;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.baoz.ibatis.IService.IPersonService;
import com.baoz.ibatis.entity.Person;
import com.opensymphony.xwork2.Action;
public class PersonAction implements Action {
private IPersonService personService;
private List list;
private Person person;
private String method;
private String id;
public Person getPerson() {
return person;
}
public void setPerson(Person person) {
this.person = person;
}
public String execute() throws Exception {
if(method != null && !method.equals("")){
return (String)MethodUtils.invokeMethod(this, method, new Object[]{});
}
return null;
}
public String list(){
list = this.getPersonService().queryList();
return "list";
}
public String addOrEdit(){
if(person.getId() != null ){
this.getPersonService().update(person);
}else{
this.getPersonService().insert(person);
}
return list();
}
public String toEdit(){
if(id != null && !id.equals("")){
int editId = Integer.parseInt(id);
person = getPersonService().readForid(editId);
}
return "add";
}
public String delete(){
if(id != null && !id.equals("")){
int deleteId = Integer.parseInt(id);
this.getPersonService().delete(deleteId);
}
return list();
}
public IPersonService getPersonService() {
if(personService == null){
ApplicationContext context = new ClassPathXmlApplicationContext("bean_main.xml");
personService=(IPersonService)context.getBean("personService");
}
return personService;
}
public void setPersonService(IPersonService personService) {
this.personService = personService;
}
public String getMethod() {
return method;
}
public void setMethod(String method) {
this.method = method;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public List getList() {
return list;
}
public void setList(List list) {
this.list = list;
}
}
