【问题描述】：
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。我尝试了以下事情：
- 在 persistence.xml 中：
添加了以下编织规范。
<property name="eclipselink.weaving" value="static" />
- 在 DBConfig.java 中，我已经配置了 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，我按照eclipselink documentation 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（构建时间）编织。当我使用maven install 创建战争时，persistence.xml 中列出的实体已成功编织。但是当我将战争部署到 tomcat 中时，它会给出以下异常：

我已经尝试将eclipselink.weaving 设置为false。但它仍然给出同样的错误。我不知道它为什么要寻找LoadTimeWeaver。请建议我在这里缺少什么。
更新：
我已经在github上传了包含eclipselink、spring mvc、spring data jpa、sitemesh的启动项目
