IDEA使用maven创建Spring-Spring-MVC-hibernate总结

目录结构如下 首先看一下数据库 t_class和t_studentmaven   pom如下   创建maven请参考我的上一篇文章   <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"> <modelVersion>4.0.0</modelVersion><groupId>com.my</groupId><artifactId>SpringMvc_Spring_Hibernate</artifactId><packaging>war</packaging><version>1.0-SNAPSHOT</version><name>SpringMvc_Spring_Hibernate Maven Webapp</name><url>http://maven.apache.org</url><properties><!-- spring版本号 --><spring.version>4.0.4.RELEASE</spring.version><hibernate.version>4.3.8.Final</hibernate.version></properties><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version><scope>test</scope></dependency><!-- spring核心包 --><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aspects</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-orm</artifactId><version>${spring.version}</version></dependency><!-- json数据 --><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.24</version></dependency><!--阿里云的数据源--><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.0.28</version></dependency><!--数据库--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.40</version></dependency><!--hibernate--><!-- hibernate --><dependency><groupId>org.hibernate</groupId><artifactId>hibernate-core</artifactId><version>${hibernate.version}</version></dependency><dependency><groupId>org.hibernate</groupId><artifactId>hibernate-ehcache</artifactId><version>${hibernate.version}</version></dependency><!-- https://mvnrepository.com/artifact/log4j/log4j --><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version></dependency><!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind --><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.8.5</version></dependency></dependencies><build><finalName>SpringMvc_Spring_Hibernate</finalName></build></project>数据库有了   实体bean和hibernate的映射文件是有idea反向工程生成的  TClassEntitypackage com.my.bean;import java.io.Serializable;/*** Created by heyongjie on 2017/2/26.*/public class TClassEntity implements Serializable{private Integer cId;private String cName;private Integer teacher;public Integer getcId() {return cId;}public void setcId(Integer cId) {this.cId = cId;}public String getcName() {return cName;}public void setcName(String cName) {this.cName = cName;}public Integer getTeacher() {return teacher;}public void setTeacher(Integer teacher) {this.teacher = teacher;}}TStudentEntity

hibernate     bean映射文件    因为使用的是maven   maven有约束  所以必须放在maven的resourse目录下面 TclassEntity    映射文件 <?xml version='1.0' encoding='utf-8'?><!DOCTYPE hibernate-mapping PUBLIC"-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"><hibernate-mapping><class name="com.my.bean.TClassEntity" table="t_class" schema="test" lazy="false"><id name="cId"><column name="c_id" sql-type="int(11)"/></id><property name="cName"><column name="c_name" sql-type="varchar(30)" length="30"/></property><property name="teacher"><column name="teacher" sql-type="int(11)"/></property></class></hibernate-mapping>TStudentEntity    映射文件

因为要做分页，所以需要一个分页beanpackage com.my.bean;import java.io.Serializable;import java.util.ArrayList;import java.util.List;/*** Created by heyongjie on 2017/3/13.*/public class PageBean<E> implements Serializable{private int pageNo; // 每页显示页数private int showNo; // 当前显示页数private int countNo; // 总共的页数private List<E> lists = new ArrayList<E>(); // 这页的数据public int getPageNo() {return pageNo;}public void setPageNo(int pageNo) {this.pageNo = pageNo;}public int getShowNo() {return showNo;}public void setShowNo(int showNo) {this.showNo = showNo;}public int getCountNo() {return countNo;}public void setCountNo(int countNo) {this.countNo = countNo;}public List<E> getLists() {return lists;}public void setLists(List<E> lists) {this.lists = lists;}@Overridepublic String toString() {return "PageBean{" +"pageNo=" + pageNo +", showNo=" + showNo +", countNo=" + countNo +", lists=" + lists +'}';}}现在看一下spring的配置文件 因为需要查看日志  所以需要导入一个   log4j.properties 文件  如下  log4j.rootLogger=DEBUG,Console,Filelog4j.appender.Console=org.apache.log4j.ConsoleAppenderlog4j.appender.Console.Target=System.outlog4j.appender.Console.layout=org.apache.log4j.PatternLayoutlog4j.appender.Console.layout.ConversionPattern=[%c]%m%nlog4j.appender.File=org.apache.log4j.RollingFileAppenderlog4j.appender.File.File=mybatis.loglog4j.appender.File.MaxFileSize=10MBlog4j.appender.File.Threshold=ALLlog4j.appender.File.layout=org.apache.log4j.PatternLayoutlog4j.appender.File.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%c]%m%n开闭原则的原因  我们将数据库的配置如用户密码  放在外面   db.properties这里面做了防止乱码的处理 jdbc_url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNulljdbc_user=rootjdbc_password=123456spring.xml<?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:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <!--从外部读取数据信息 --><context:property-placeholder location="classpath:db.properties"/><!--扫描 --><context:component-scan base-package="com.my.*"/><!--配置阿里云的数据源--><bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"><!-- 基本属性 url、user、password --><property name="url" value="${jdbc_url}"/><property name="username" value="${jdbc_user}"/><property name="password" value="${jdbc_password}"/><!-- 配置初始化大小、最小、最大 --><property name="initialSize" value="1"/><property name="minIdle" value="1"/><property name="maxActive" value="20"/><!-- 配置获取连接等待超时的时间 --><property name="maxWait" value="60000"/><!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 --><property name="timeBetweenEvictionRunsMillis" value="60000"/><!-- 配置一个连接在池中最小生存的时间，单位是毫秒 --><property name="minEvictableIdleTimeMillis" value="300000"/><property name="validationQuery" value="SELECT 'x'"/><property name="testWhileIdle" value="true"/><property name="testOnBorrow" value="false"/><property name="testOnReturn" value="false"/><!-- 打开PSCache，并且指定每个连接上PSCache的大小 --><property name="poolPreparedStatements" value="true"/><property name="maxPoolPreparedStatementPerConnectionSize" value="20"/><!-- 配置监控统计拦截的filters --><property name="filters" value="stat"/></bean><!--配置hibernate--><bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource"/><property name="mappingResources"><list><value>hibernateCfg/TClassEntity.hbm.xml</value><value>hibernateCfg/TStudentEntity.hbm.xml</value></list></property><property name="hibernateProperties"><value>hibernate.dialect=org.hibernate.dialect.MySQLDialecthibernate.show_sql =true<!-- hibernate.hbm2ddl.auto=create --></value></property></bean><!--配置事物管理器 --><bean id="transactionManager"class="org.springframework.orm.hibernate4.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory"/></bean></beans>
