SSH整合（Spring+SpringMVC+Hibernate）註解版

SSH整合
1.首先我們建立一個Maven專案
然後 我們匯入jar包 因為 是maven所以是節點
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <parent> <artifactId>Y2_SSH</artifactId> <groupId>cn.happy</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>SSH_MVC</artifactId> <packaging>war</packaging> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <maven.compiler.encoding>UTF-8</maven.compiler.encoding> <spring.version>4.3.2.RELEASE</spring.version> <hibernate.version>5.2.2.Final</hibernate.version> </properties> <name>SSH_MVC Maven Webapp</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.3</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>com.oracle</groupId> <artifactId>ojdbc6</artifactId> <version>11.2.0.1.0</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>${hibernate.version}</version> </dependency> <!--jta的jar包--> <dependency> <groupId>javax.transaction</groupId> <artifactId>jta</artifactId> <version>1.1</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.39</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.9</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-dbcp2</artifactId> <version>2.1.1</version> </dependency> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> </dependencies> <build> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> </resources> </build> </project>
2.然後我們看一下架構：
3.我們先寫實體類 我們 用的 是註解版的 所以 不需要小配置
package cn.happy.beans; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; /** * Created by linlin on 2017/10/13. */ @Entity public class Dept { @Id @GeneratedValue private Integer deptno; @Column private String deptname; public Integer getDeptno() { return deptno; } public void setDeptno(Integer deptno) { this.deptno = deptno; } public String getDeptname() { return deptname; } public void setDeptname(String deptname) { this.deptname = deptname; } }
4.dao層
package cn.happy.dao;
import cn.happy.beans.Dept;
import org.hibernate.Session;
/**
* Created by linlin on 2017/10/13.
*/
public interface IDeptDao {
public int addDept(Dept dept);
}
package cn.happy.dao; import cn.happy.beans.Dept; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.springframework.stereotype.Repository; import org.springframework.transaction.annotation.Transactional; import javax.annotation.Resource; import java.io.Serializable; /** * Created by linlin on 2017/10/13. */ @Repository("deptDAO") public class DeptDaoImpl implements IDeptDao{ @Resource private SessionFactory sessionFactory; public int addDept(Dept dept) { Serializable count = sessionFactory.getCurrentSession().save(dept); return (Integer) count; } public SessionFactory getSessionFactory() { return sessionFactory; } public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } }
servier層：
package cn.happy.service;
import cn.happy.beans.Dept;
/**
* Created by linlin on 2017/10/13.
*/
public interface IDeptService {
public int addDept(Dept dept);
}
package cn.happy.service;
import cn.happy.beans.Dept;
import cn.happy.dao.IDeptDao;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import javax.annotation.Resource;
/**
* Created by linlin on 2017/10/13.
*/
@Service("deptService")
public class DeptServiceImpl implements IDeptService{
@Resource()
private IDeptDao dao;
@Transactional
public int addDept(Dept dept) {
int result=dao.addDept(dept);
return result;
}
public IDeptDao getDao() {
return dao;
}
public void setDao(IDeptDao dao) {
this.dao = dao;
}
}
controller層：
package cn.happy.controller;
import cn.happy.beans.Dept;
import cn.happy.service.IDeptService;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.annotation.Resource;
/**
* Created by linlin on 2017/10/13.
*/
@Controller
public class DeptController {
@Resource(name="deptService")
private IDeptService deptService;
@RequestMapping("/adds")
public String add(Dept dept){
deptService.addDept(dept);
return "index";
}
public IDeptService getDeptService() {
return deptService;
}
public void setDeptService(IDeptService deptService) {
this.deptService = deptService;
}
}
我們寫配置檔案 大配置：

還有一個就是web.xml
這個是我們必須寫的

ok.....完成 了
