SSM框架搭建

Posted 2022-12-04 z_fishLong

常用框架

Springmvc+spring+hibernate

Springmvc+spring+mybatis

Spring+Struts2+hibernate

开发步骤：

1） 画草图

 

 

2） 创建表

3） 创建web工程

4） 导入jar，mybatis包，spring(springmvc)，数据库驱动…

spring-orm-3.2.2.jar
spring-tx-3.2.2.jar
spring-web-3.2.2.jar
spring-webmvc-3.2.2.jar

5） 创建PO实体对象

import java.io.Serializable;
import java.util.List;
public class Person implements Serializable 
	private Integer id;
	private String name;
	private Integer age;
	private String remark;
	public Integer getId() 
		return id;
	
	public void setId(Integer id) 
		this.id = id;
	
	public String getName() 
		return name;
	
	public void setName(String name) 
		this.name = name;
	
	public Integer getAge() 
		return age;
	
	public void setAge(Integer age) 
		this.age = age;
	
	public String getRemark() 
		return remark;
	
	public void setRemark(String remark) 
		this.remark = remark;
	

6） 创建mapper映射文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.ilmare.ssm.mapper.PersonMapper">
	<resultMap type="com.ilmare.ssm.domain.Person" id="personRM">
		<id property="id" column="ID"/>
		<result property="name" column="USER_NAME"/>
		<result property="age" column="AGE"/>
		<result property="remark" column="REMARK"/>
	</resultMap>
	
	<!-- 带条件查询 -->
	<select id="find" parameterType="map" resultMap="personRM">
		select * from person
		where 1=1
		<if test="name!=null"> and user_name like #name</if>
		<if test="ageStart!=null"> and age>#ageStart</if>
		<if test="ageEnd!=null"><![CDATA[ and age<=#ageEnd]]></if>
	</select>
</mapper>

7） 创建Mapper接口

import java.util.List;
import java.util.Map;
public interface PersonMapper 
	public List<Person> find(Map map);

8） 创建PersonDao接口

import java.util.List;
import java.util.Map;
public interface PersonDao 
	public List<Person> find(Map map);

9） 创建PersonDaoImpl

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.support.SqlSessionDaoSupport;
import org.springframework.stereotype.Repository;
import com.ilmare.ssm.bean.Person;
import com.ilmare.ssm.dao.PersonDao;
import com.ilmare.ssm.mapper.PersonMapper;

@Repository("personDao")
public class PersonDaoImpl extends SqlSessionDaoSupport  implements PersonDao
	//这两个随便注入一个
	//sqlSessionTemplate
	//sqlSessionFactory
	
	/*
	 * mybatis3.0.0+mybatis-psring1.0.0无需，整合包自己注入
	 * mybatis3.2.2+mybatis-spring1.2.0 必须自己注入sqlSessionFactory；
	 */
        @Resource
	public void setSqlSessiionFactory(SqlSessionFactory sqlSessionFactory) 
		super.setSqlSessionFactory(sqlSessionFactory);
	
	
	@Override
	public List<Person> find(Map map) 
		PersonMapper personMapper=this.getSqlSession().getMapper(PersonMapper.class);
		return personMapper.find(map);
	

	

10） 创建PersonService接口

import java.util.List;
import java.util.Map;
import com.ilmare.ssm.domain.Person;
public interface PersonService 
	public List<Person> find(Map map);

11） 创建PersonServiceImpl

@Service
public class PersonServiceImpl implements PersonService 
	@Resource
	PersonDao personDao;
	
	public List<Person> find(Map map)
		return personDao.find(map);
	

12） 创建PersonController

@Controller
public class PersonController 
	@Resource
	PersonService personService;
	
	//查询，将查询结果传递到页面
	@RequestMapping("/person/list.action")	//Controller加载时会自动创建访问路径 /person/list;/person/list.action
	public String list(Model model)
		List<Person> personList = personService.find(null);
		model.addAttribute("personList", personList);		//传递到页面
		
		return "/person/jPersonList.jsp";
	

13） 创建列表页面jPersonList.jsp

14） 配置sqlMapConfig.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

</configuration>

15） 配置application-context.xml
