Spring，Hibernate 检查我的 Maven Shade JAR 中的每个 jar

Question

当我从java -jar foo.jar 运行我的 jar 时，就像这些行数以千计一样，所以应用程序至少需要 1 分钟才能启动。

我正在使用 Maven Shade 创建我的 JAR：

<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.0</version>

Spring 和 Hibernate 配置：

<bean id="entityManagerFactory" 
      class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
  <property name="dataSource" ref="dataSource"/>
</bean>
<bean id="transactionManager"
      class="org.springframework.orm.jpa.JpaTransactionManager">
  <property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
<tx:annotation-driven transaction-manager="transactionManager"/>

如何过滤它以不搜索 POM 下载的所有 JAR？

编辑：

完整的 Spring 配置：

<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:tx="http://www.springframework.org/schema/tx"
   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/tx
    http://www.springframework.org/schema/tx/spring-tx-3.1.xsd">

<context:component-scan base-package="my.foo.bar" />

<context:property-placeholder location="classpath:/config/database.properties"/>

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="${database.driverClassName}"/>
    <property name="url" value="${database.url}"/>
    <property name="username" value="${database.username}"/>
    <property name="password" value="${database.password}"/>
</bean>

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource"/>
</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
<tx:annotation-driven transaction-manager="transactionManager"/>

完全持久化：

 <?xml version="1.0" encoding="UTF-8" standalone="no"?>
<persistence 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_1_0.xsd"
         version="1.0">
<persistence-unit name="persistenceUnit">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <properties>
        <property name="hibernate.dialect" value="dialect.ImprovedH2Dialect"/>
        <property name="hibernate.default_schema" value="ags" />
        <property name="hibernate.show_sql" value="true"/>
        <!-- value="create" to build a new database on each run; value="update" to modify an existing database; value="create-drop" means the same as "create" but also drops tables when Hibernate closes; value="validate" makes no changes to the database -->
        <property name="hibernate.hbm2ddl.auto" value="create"/>
        <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy"/>
        <property name="hibernate.connection.charSet" value="UTF-8"/>
    </properties>
</persistence-unit>

你需要在persistence.xml中调整一些设置，添加：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<persistence 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_1_0.xsd"
         version="1.0">
<persistence-unit name="persistenceUnit">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <class>my.foo.bar</class>
    <exclude-unlisted-classes>true</exclude-unlisted-classes>
    <properties>
        <property name="hibernate.dialect" value="dialect.ImprovedH2Dialect"/>
        <property name="hibernate.default_schema" value="ags" />
        <property name="hibernate.show_sql" value="true"/>
        <!-- value="create" to build a new database on each run; value="update" to modify an existing database; value="create-drop" means the same as "create" but also drops tables when Hibernate closes; value="validate" makes no changes to the database -->
        <property name="hibernate.hbm2ddl.auto" value="create"/>
        <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy"/>
        <property name="hibernate.connection.charSet" value="UTF-8"/>
    </properties>
</persistence-unit> 

并指定所有实体类。

Answer 2

尝试添加到你的 persistence.xml

 <exclude-unlisted-classes>true</exclude-unlisted-classes>

 <class>my.foo.bar.Entity1</class>
 <class>my.foo.bar.Entity2</class>
...
 <class>my.foo.bar.EntityN</class>

并删除<class>my.foo.bar</class>

而且，也许<jar-file>jar_with_my_foo_bar_Entity.jar</jar-file> 会有所帮助
