搭建SpringMVC4.x+Spring4.x+Hibernate4.x(非Maven版)

1.创建数据库ssh-pro，使用utf-8编码

2.首先创建一个Java Web项目输入相关参数点击下一步，知道出现要求创建web.xml，勾选创建web.xml，点击完成即可





3.将ssh所需要的jar全部复制到WebContent/WEB-INF/lib文件夹下，程序会自动将jar添加到编译环境中

4.在ssh项目下创建一个Source Folder的文件夹名为config，用来放一些配置文件。创建test，用来放置测试代码

5.再src下面创建org.ccnu.dao，来存放数据操作的相关代码。创建org.ccnu.service，来存放服务的相关代码。创建org.ccnu.entity，来存放数据模型代码。创建org.ccnu.controller，来存放控制层相关代码。

6.项目第一步是创建数据连接层

在config里创建config.properties，注意里面不能出现中文。代码如下：

#application configs

#jdbc c3p0 config
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssh-pro?useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=root

#hibernate config
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.show_sql=true
hibernate.format_sql=false
hibernate.hbm2ddl.auto=update
hibernate.c3p0.validate=true
hibernate.temp.use_jdbc_metadata_defaults=false

#second cache
cache.use_second_level_cache=true
cache.use_query_cache=true
cache.region.factory_class=org.hibernate.cache.ehcache.EhCacheRegionFactory
cache.provider_configuration_file_resource_path=ehcache.xml

##############################################################
#file save path
normal_file_path=/home/lyt/TmpDemo

7.创建相关配置文件

WEB-INF的web-xml来配置整个项目的数据，代码如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

</session-config>
</web-app>

在config文件夹里创建相关的配置文件

spring-mvc.xml来配置控制层的相关操作。代码如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd"> 
<!-- 自动扫描@Controller注入为bean -->
<context:component-scan base-package="org.ccnu.controller"/>

<!-- 以下为SpringMVC配置 -->
<mvc:annotation-driven>
<!-- 返回json数据，@response使用 -->
<mvc:message-converters register-defaults="true">
<bean
class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">

</list>
</property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
<mvc:resources mapping="/resources/**" location="/resources/" />

<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".jsp" />
</bean>

<!-- 文件上传下载 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>
</beans>

spring-hibernate.xml来配置数据操作的相关信息。代码如下：

<?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:tx="http://www.springframework.org/schema/tx"

xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd">

<!-- 配置数据源 c3p0 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close">
<property name="driverClass" value="${jdbc.driver}" />
<property name="jdbcUrl" value="${jdbc.url}" />
<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />

<!-- 请求超时时间 -->
<property name="checkoutTimeout" value="30000" />
<!-- 每60秒检查所有连接池中的空闲连接。默认值: 0，不检查 -->
<property name="idleConnectionTestPeriod" value="30" />
<!-- 连接数据库连接池最大空闲时间 -->

<!-- 连接池初始化连接数 -->
<property name="initialPoolSize" value="5" />
<property name="minPoolSize" value="5" />
<property name="maxPoolSize" value="20" />
<!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。默认值: 3 -->
<property name="acquireIncrement" value="5" />
</bean>

<!-- 配置hibernate的SessionFactory -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<!-- 注入数据源 相关信息 -->
<property name="dataSource" ref="dataSource" />
<!-- hibernate配置信息 -->

<property name="sessionFactory" ref="sessionFactory" />
</bean>
<!-- 使用基于注解的事物 -->
<tx:annotation-driven transaction-manager="transactionManager" />

</beans>

8.在entity创建User类，代码如下：

package org.ccnu.entity;

import java.io.Serializable;
import java.util.Date;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
import javax.persistence.UniqueConstraint;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;

import org.ccnu.util.DateAdapter;
import org.hibernate.annotations.GenericGenerator;

import com.fasterxml.jackson.annotation.JsonFormat;

/**
* 用户
* @author liuyuantao
*
*/
@XmlRootElement
@Entity
@Table(name = "user", catalog = "ssh-pro",
uniqueConstraints = @UniqueConstraint(columnNames = "userName") )
public class User implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private String id;
private String userName;
private String password;
private String fullName;
private String email;
private Date birthDay;
@Id
@GenericGenerator(name = "idGenerator", strategy = "uuid")
@GeneratedValue(generator = "idGenerator")
@Column(length = 40)
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
@Column(name = "username", nullable = true, length = 40)
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
@Column(name = "password", nullable = true, length = 40)
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Column(name = "fullName", nullable = true, length = 40)
public String getFullName() {
return fullName;
}
public void setFullName(String fullName) {
this.fullName = fullName;
}
@Column(name = "email", nullable = true, length = 40)
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
@Temporal(TemporalType.DATE)
@Column(name = "addTime", length = 19)
@XmlJavaTypeAdapter(DateAdapter.class)
@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd",
timezone = "GMT+8")
public Date getBirthDay() {
return birthDay;
}
public void setBirthDay(Date birthDay) {
this.birthDay = birthDay;
}

}

9.在service创建UserService，在dao层创建userDao和BaseDao

package org.ccnu.dao;

import java.io.Serializable;
import java.lang.reflect.ParameterizedType;
import java.util.List;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;

/**
* 基础公共Dao类
*
* @author liuyuantao
* @param <T>
* @param <PK>
*/
public class BasicDao<T, PK extends Serializable> {
protected Class<T> entityClass;

@SuppressWarnings("unchecked")
public BasicDao() {
entityClass = (Class<T>) ((ParameterizedType) getClass()
.getGenericSuperclass()).getActualTypeArguments()[0];
}

@Autowired
private SessionFactory sessionFactory;

/**
* 获取当前线程的session
*
* @return
*/
private Session getCurrentSession() {
return this.sessionFactory.getCurrentSession();
}

@SuppressWarnings("unchecked")
public T load(PK id) {
return (T) this.getCurrentSession().load(entityClass, id);
}

@SuppressWarnings("unchecked")
public T get(PK id) {
return (T) this.getCurrentSession().get(entityClass, id);
}

public List<T> findAll() {
String sql = "select e from " + entityClass.getSimpleName() + " e";
@SuppressWarnings("unchecked")
List<T> list = this.getCurrentSession().createQuery(sql).list();
return list != null ? list : null;
}

public void persist(T entity) {
this.getCurrentSession().persist(entity);
}

@SuppressWarnings("unchecked")
public PK save(T entity) {
return (PK) this.getCurrentSession().save(entity).toString();
}

@SuppressWarnings("unchecked")
public PK merge(T entity) {
return (PK) this.getCurrentSession().merge(entity);
}

public void saveOrUpdate(T entity) {
this.getCurrentSession().saveOrUpdate(entity);
}

public void delete(T entity) {
this.getCurrentSession().delete(entity);
}

public void flush() {
this.getCurrentSession().flush();
}
}

package org.ccnu.dao;

import java.util.List;

import org.ccnu.entity.User;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

@Repository(value = "userDao")
public class UserDao extends BasicDao<User, String> {
@Autowired
private SessionFactory sessionFactory;

/**
* 获取当前线程的session
*
* @return
*/
private Session getCurrentSession() {
return sessionFactory.getCurrentSession();// 还是可以得到session
}

/**
* 通过姓名模糊查找用户
*
* @param fullName
* @return
*/
@SuppressWarnings("unchecked")
public List<User> findUserByFullName(String fullName) {
String sql = "select model from User model where model.fullName like :fullName";
Query query = this.getCurrentSession().createQuery(sql);
query.setParameter("fullName", "%" + fullName + "%");
return query.list();
}
}

package org.ccnu.service;

import java.util.List;

import org.ccnu.dao.UserDao;
import org.ccnu.entity.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Transactional
@Service("userService")
public class UserService {
@Autowired
private UserDao userDao;

@Transactional(readOnly = false)
public String saveUser(User user) {
return userDao.save(user);
}

@Transactional()
public List<User> findUserByFullName(String fullName) {
return userDao.findUserByFullName(fullName);
}
}
