Spring DATA jpa 持久化实例 1(转)

JPA  JAVA Persistence API 持久化API 。
由于hibernate + spring + spring security 验证时 处理用户密码验证检索库无法进行依赖注入，所以选择JPA研究看看。
首先当然是准备活动了：


1、下载开发所需要的发布包。
1）spring-framework-3.1.2.RELEASE-with-docs.zip　　
下载地址：http://www.springsource.org/spring-framework
2）hibernate-release-4.1.6.Final.zip
下载地址：http://olex.openlogic.com/packages/hibernate
3）Spring Data JPA
Spring Data JPA
下载地址：http://www.springsource.org/spring-data/jpa
Spring Data Commons
下载地址：http://www.springsource.org/spring-data/commons
4）其他一些依赖包可以从 http://ebr.springsource.com/repository/app/library
                         http://ebr.springsource.com/repository/app/bundle
    上查找下载


2、依赖包明细：


  使用的是spring3.2.3
          spring-data-jpa-1.3.4.RELEASE.jar
          spring-data-commons-1.5.0.RELEASE.jar
  ebr.springsource.com中可以找到：
          com.springsource.antlr-2.7.7.jar
          com.springsource.net.sf.cglib-2.2.0.jar
          com.springsource.org.aopalliance-1.0.0.jar
          com.springsource.org.apache.commons.logging-1.1.1.jar
          com.springsource.org.aspectj.weaver-1.5.4.jar
   其他包：
          slf4j-api-1.6.4.jar
            slf4j-log4j12-1.6.4.jar
  mysql-connector-java
        log4j-1.2.14.jar
         commons-lang3-3.1.jar
 
hibernate 4.2.3 lib:

hibernate-commons-annotations-4.0.1.Final.jar hibernate-core-4.1.6.Final.jar hibernate-entitymanager-4.1.6.Final.jar hibernate-jpa-2.0-api-1.0.1.Final.jar javassist-3.15.0-GA.jar jboss-logging-3.1.0.GA.jar jboss-transaction-api_1.1_spec-1.0.0.Final.jar
javassist-3.12.0.GA.jar
dom4j-1.6.1.jar
antlr-2.7.7.jar


3、JPA配置文件persistence.xml
<?xml version="1.0" encoding="UTF-8"?> <persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"> <persistence-unit name="MYJPATEST" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <properties> <!--配置Hibernate方言 --> <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect" /> <!--配置数据库驱动 --> <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" /> <!--配置数据库用户名 --> <property name="hibernate.connection.username" value="root" /> <!--配置数据库密码 --> <property name="hibernate.connection.password" value="root" /> <!--配置数据库url --> <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/spring_data_jpa?useUnicode=true&amp;characterEncoding=UTF-8" /> <!--设置外连接抓取树的最大深度 --> <property name="hibernate.max_fetch_depth" value="3" /> <!--自动输出schema创建DDL语句 --> <property name="hibernate.hbm2ddl.auto" value="update" /> <property name="hibernate.show_sql" value="true" /> <property name="hibernate.format_sql" value="true" /> <property name="javax.persistence.validation.mode" value="none"/>
 
<!--增加cache -->

<property name="hibernate.cache.provider_class" value="net.sf.ehcache.hibernate.SingletonEhCacheProvider" /> <property name="hibernate.cache.use_query_cache" value="true" /> <property name="hibernate.cache.use_second_level_cache" value="true" /> <property name="hibernate.generate_statistics" value="true" /> <property name="hibernate.use_sql_comments" value="true" />     

</properties>
</persistence-unit>
</persistence>


4、Spring配置文件applicationContext.xml
在 beans中 必须加入 default- default-lazy-init="true"
自动寻找资源对应根据name来确定，以及延迟加载是确定。
 
<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:p="http://www.springframework.org/schema/p" xmlns:cache="http://www.springframework.org/schema/cache" xmlns:jpa="http://www.springframework.org/schema/data/jpa" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.1.xsd http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa.xsd"
  default- default-lazy-init="true"  >
<context:annotation-config /> <context:component-scan base-package="com.test"/> <!-- 定义实体管理器工厂 --> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="persistenceUnitName" value="MYJPATEST"/> </bean> <!-- 配置事务管理器 --> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <!-- 启用 annotation事务--> <tx:annotation-driven transaction-manager="transactionManager"/> <!-- 配置Spring Data JPA扫描目录--> <jpa:repositories base-package="com.test.repository"/> </beans>


5、web.xml 配置
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <display-name></display-name> <!-- log4j配置 --> <context-param> <param-name>webAppRootKey</param-name> <param-value>springdatajpa.root</param-value> </context-param> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>classpath:log4j.properties</param-value> </context-param> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <!-- 编码过滤器 --> <filter> <filter-name>characterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置spring监听器 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置缓存清除监听器,负责处理由 JavaBean Introspector 功能而引起的缓存泄露 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>

6、日志配置

log4j.rootLogger=INFO,CONSOLE,FILE log4j.addivity.org.apache=true # 应用于控制台 log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender log4j.appender.Threshold=INFO log4j.appender.CONSOLE.Target=System.out log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout log4j.appender.CONSOLE.layout.ConversionPattern=[framework] %d - %c -%-4r [%t] %-5p %c %x - %m%n #log4j.appender.CONSOLE.layout.ConversionPattern=[start]%d{DATE}[DATE]%n%p[PRIORITY]%n%x[NDC]%n%t[THREAD] n%c[CATEGORY]%n%m[MESSAGE]%n%n #应用于文件 log4j.appender.FILE=org.apache.log4j.DailyRollingFileAppender log4j.appender.FILE.File=${springdatajpa.root}/springdatajpa.log log4j.appender.FILE.Append=true log4j.appender.FILE.layout=org.apache.log4j.PatternLayout log4j.appender.FILE.layout.ConversionPattern=[framework] %d - %c -%-4r [%t] %-5p %c %x - %m%n
