静态编织eclipselink jpa与spring和tomcat

我正在尝试使用maven使用Eclipselink+Spring+JPA实现静态编织。我已经用Java配置配置了我的spring项目，没有context.xml

在persistence.xml中：

增加了以下编织规范。

<property name="eclipselink.weaving" value="static" />

在DBConfig.java中，我配置了bean

如下：

 @Bean()
    public DataSource getDataSource() {
        BoneCPDataSource ds = new BoneCPDataSource();
        log.debug("Driver Name : " + driverClassName);
        try {
            Class.forName(driverClassName);
        } catch (ClassNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        log.debug("DB Url : " + url);
        ds.setDriverClass(driverClassName);
        ds.setJdbcUrl(url);
        ds.setUsername(username);
        ds.setPassword(password);
        ds.setMaxConnectionsPerPartition(5);
        ds.setMinConnectionsPerPartition(2);
        ds.setAcquireIncrement(2);
        ds.setDefaultAutoCommit(false);     
        Properties props = new Properties();
        props.put("eclipselink.weaving", "static");
        try {
            ds.setProperties(props);
        } catch (Exception e) {         
            e.printStackTrace();
        }
        return ds;
    }
    @Bean(name = "em")
    public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean() {
        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(getDataSource());      
        em.setJpaDialect(jpaDialect());
        em.setPackagesToScan("com.cdl.hp50.model", "com.cdl.hp50.model.person");
        em.setPersistenceUnitName(persistenceUnitName);
        DatabasePlatform dp = new MySQLPlatform();
        em.setJpaVendorAdapter(getEclipseLinkJpaVendorAdapter());       
        return em;
    }

在pom.xml中，我根据eclipselink文档中的说明添加了以下插件：

如下：

              <plugin>
                    <groupId>de.empulse.eclipselink</groupId>
                    <artifactId>staticweave-maven-plugin</artifactId>
                    <version>1.0.0</version>
                    <executions>
                        <execution>
                            <phase>process-classes</phase>
                            <goals>
                                <goal>weave</goal>
                            </goals>
                            <configuration>
                                <persistenceXMLLocation>META-INF/persistence.xml</persistenceXMLLocation>
                                <logLevel>FINE</logLevel>
                            </configuration>
                        </execution>
                    </executions>
                    <dependencies>
                        <dependency>
                            <groupId>org.eclipse.persistence</groupId>
                            <artifactId>org.eclipse.persistence.jpa</artifactId>
                            <version>${eclipselink.version}</version>
                        </dependency>
                    </dependencies>
                </plugin>

我已经明确指定使用静态（构建时）编织。当我使用maven install创建war时，persistence.xml中列出的实体被成功编织。但当我将战争部署到tomcat时，它给出了以下例外：

我已尝试将eclipselink.weaving设置为false。但它仍然给出了同样的错误。我不知道它为什么要找LoadTimeWeaver。请告诉我我在这里缺了什么。

更新：

我已经上传了入门项目，包括eclipselink，springmvc，springdatajpa，github上的sitemesh

编辑：我想我发现了你的问题

   props.put("eclipselink.weaving", "static");
    try {
        ds.setProperties(props);

您是否正在尝试将eclipselink属性应用于数据源？如果您查看我的示例context.xml（来自下面的应用程序），则需要将jpaPropertyMap应用于LocalContainerEntityManagerFactoryBean。

因此，您应该将代码更改为

 em.setjpaPropertyMap(props)

旧答案：

首先，对于这样的问题，一个示例项目会非常好。好吧，我是为你做的，可以在以下位置找到：https://github.com/baumgartner/eclipselink-static-weaving

坏消息是：我无法重现你的问题，我的应用程序在tomcat 7上运行良好。

你检查过你的.class文件是否被静态编织插件扩展了吗？编织的文件在你的tomcat文件夹里吗？tomcat wtpwebapps文件夹中的文件是否正确？（有时同步会失败）您是否使用了JAD（java反编译器）来反编译您的类并检查它们是否得到了增强？一个增强的实体看起来是这样的：

public class asdf.User implements java.lang.Cloneable, org.eclipse.persistence.internal.weaving.PersistenceWeaved, org.eclipse.persistence.internal.descriptors.PersistenceEntity, org.eclipse.persistence.internal.descriptors.PersistenceObject, org.eclipse.persistence.queries.FetchGroupTracker, org.eclipse.persistence.internal.weaving.PersistenceWeavedFetchGroups, org.eclipse.persistence.descriptors.changetracking.ChangeTracker, org.eclipse.persistence.internal.weaving.PersistenceWeavedChangeTracking, org.eclipse.persistence.internal.weaving.PersistenceWeavedRest {

如果你部署了战争，你的应用程序能工作吗？如果你从IDE运行你的应用程序，它能工作吗？

我也曾尝试使用maven使用Eclipselink+Spring+JPA实现静态编织。一切都很好，除了提取类型从来没有工作过Lazy。最后，我找到了一个非常适合我的解决方案。
解决方案是在我的maven pom.xml中添加一个插件。

<plugin>
    <artifactId>eclipselink-staticweave-maven-plugin</artifactId>
    <groupId>au.com.alderaan</groupId>
    <version>1.0.4</version>
    <executions>
        <execution>
            <goals>
                <goal>weave</goal>
            </goals>
            <phase>process-classes</phase>
            <configuration>
                <logLevel>ALL</logLevel>
            </configuration>
        </execution>
    </executions>
    <dependencies>
        <dependency>
            <groupId>org.eclipse.persistence</groupId>
            <artifactId>eclipselink</artifactId>
            <version>${eclipselink.version}</version>
        </dependency>
    </dependencies>
</plugin>

建议由EclipseLink也
我对静态编织的唯一问题是，即使你愿意，你也不能急切地获取。因此，我使用的不是编织，而是批处理或连接获取
