的EclipseLink和Spring 3.1

我有Hibernate的工作，但我想改變的EclipseLink。我一直在尋找這個，但沒有結果的解決方案。人們建議把這兩（不在一起）的EclipseLink和Spring 3.1

<class>no.mesta.driftslogg.model.Person</class> 
<exclude-unlisted-classes>false</exclude-unlisted-classes>

persistence.xml中

persitence.xml

<?xml version="1.0" encoding="UTF-8"?> 
<persistence version="1.0" 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_1_0.xsd"> 

<persistence-unit name="cccPersistenceUnit"> 
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> 
    <exclude-unlisted-classes>false</exclude-unlisted-classes> 
    <properties> 
     <property name="eclipselink.ddl-generation" value="create-tables" /> 
     <property name="eclipselink.ddl-generation.output-mode" value="database" /> 
    </properties> 
</persistence-unit>

應用程序的context.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:p="http://www.springframework.org/schema/p"

你的錯誤是一個「待辦事項」的對象，而不是一個人。確保你已經映射了所有相關的對象。

你需要把no.mesta.driftslogg.model.Person在你的persistence.xml，你沒有這個。

對於Todo來說很抱歉。人給出了相同的結果。我正在嘗試不同的實體。對困惑感到抱歉。 – pethel

而不是使用SimpleLoadTimeWeaver（我不能得到這兩種工作），我用

<context:load-time-weaver/>

這就需要從春儀器使用Java代理的，所以你將不得不啓動JVM有agument告訴它在哪裏可以找到。類似於

-javaagent:spring-instrument-3.1.1.RELEASE.jar
