Hibernate和Struts2 java.lang.NullPointerException w/CRUD演示

我有一个项目，我正在一起使用Hibernate和Struts2，我对它们都是新手

我很难用Hibernate和Struts2组合来计算CRUD过程。我想用一种特定的方式来做这件事，但我遇到了麻烦。为了复制我在主要项目之外遇到的问题，我从本教程下载了WAR，并成功地使其运行：

然后，我通过以下更改将Hibernate引入到它中：

1） 首先，我将真实项目中的JAR添加到这个项目中，以确保我运行的所有内容都是相同的版本。关键是我正在起诉Hibernate 3、Struts2和FullHibernateCore插件来链接它们。关于更多细节，以下是我正在使用的罐子：

antlr-2.7.7.jar
commons-collections-3.2.1.jar
commons-fileupload-1.2.2.jar
commons-io-2.0.1.jar
commons-lang-2.5.jar
commons-logging-1.1.1.jar
commons-logging-api-1.1.jar
dom4j-1.6.1.jar
freemarker-2.3.18.jar
hibernate3.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
hibernate-testing.jar
hibernate-validator.jar
javassist-3.15.0-GA.jar
jboss-logging-3.1.0.CR2.jar
jboss-transaction-api_1.1_spec-1.0.0.Final.jar
jta-1.1.jar
log4j-1.2.15.jar
mysql-connector-java-5.1.18-bin.jar
ognl-3.0.4.jar
slf4j-api-1.6.1.jar
slf4j-log4j12-1.6.1.jar
struts2-core-2.3.1.2.jar
struts2-fullhibernatecore-plugin-2.2.2-GA.jar
xwork-core-2.3.1.2.jar

2） 添加了hibernate.cfg.xml，如下所示：

5） 创建了com.rwblackburn.struts2.tutorial.dao.EmployeeHibernateDao，它实现了EmployeeDao

package com.rwblackburn.struts2.tutorial.dao;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.Transaction;

import com.aurifa.struts2.tutorial.dao.EmployeeDao;
import com.aurifa.struts2.tutorial.model.Employee;
import com.googlecode.s2hibernate.struts2.plugin.annotations.SessionTarget;
import com.googlecode.s2hibernate.struts2.plugin.annotations.TransactionTarget;

public class EmployeeHibernateDao implements EmployeeDao {
@SessionTarget
protected Session session;

@TransactionTarget
protected Transaction transaction;

@SuppressWarnings("rawtypes")
@Override
public List getAllEmployees() {
    return session.createQuery( "from Employee" ).list();
}

@Override
public Employee getEmployee(Integer id) {
    Employee emp = new Employee();
    session.load(emp, id );
    return emp;
}

@Override
public void update(Employee emp) {
    session.update(emp);

}

@Override
public void insert(Employee emp) {
    session.save(emp);
}

@Override
public void delete(Integer id) {
    Employee emp = new Employee();
    session.load(emp, id );
    session.delete(emp);
}

}

6） 创建了com.rwblackburn.struts2.tutorial.dao.DepartmentHibernateDao，它实现了DepartmentDao

package com.rwblackburn.struts2.tutorial.dao;

import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;

import org.hibernate.Session;
import org.hibernate.Transaction;

import com.aurifa.struts2.tutorial.dao.DepartmentDao;
import com.aurifa.struts2.tutorial.model.Department;
import com.googlecode.s2hibernate.struts2.plugin.annotations.SessionTarget;
import com.googlecode.s2hibernate.struts2.plugin.annotations.TransactionTarget;

public class DepartmentHibernateDao implements DepartmentDao {
@SessionTarget
protected Session session;

@TransactionTarget
protected Transaction transaction;

@SuppressWarnings("rawtypes")
@Override
public List getAllDepartments() {
    return session.createQuery( "from Department" ).list();
}

@SuppressWarnings("rawtypes")
@Override
public Map getDepartmentsMap() {
    Map<Integer, Department> departmentsMap = new HashMap<Integer, Department>();
    Iterator iter = this.getAllDepartments().iterator();
    while( iter.hasNext() ) {
        Department dept = (Department)iter.next();
        departmentsMap.put(dept.getDepartmentId(), dept );
    }
    return departmentsMap;
}

}

当我进行调试跟踪时，我可以确认DepartmentHibernateDao中的会话和事务变量实际上为null

在进行了大量搜索后，我发现了以下线索：

这似乎是我遇到的同一个问题。但是，即使我将Struts版本降级为2.1.6，我仍然存在问题，以下是我的新库：

 antlr-2.7.2.jar
 commons-collections-3.2.jar
 commons-fileupload-1.2.1.jar
 commons-io-1.3.2.jar
 commons-lang-2.3.jar
 commons-logging-1.0.4.jar
 commons-logging-api-1.1.jar
 commons-validator-1.3.1.jar
 dom4j-1.6.1.jar
 freemarker-2.3.13.jar
 hibernate3.jar
 hibernate-jpa-2.0-api-1.0.1.Final.jar
 hibernate-testing.jar
 hibernate-validator.jar
 javassist-3.15.0-GA.jar
 jboss-logging-3.1.0.CR2.jar
 jboss-transaction-api_1.1_spec-1.0.0.Final.jar
 jta-1.1.jar
 log4j-1.2.15.jar
 mysql-connector-java-5.1.18-bin.jar
 ognl-2.6.11.jar
 slf4j-api-1.6.1.jar
 slf4j-log4j12-1.6.1.jar
 struts2-core-2.1.6.jar
 struts2-fullhibernatecore-plugin-2.2.2-GA.jar
 xwork-2.1.2.jar

此外，我还通过在一些hibernate会话调用之前添加“if（session==null）”检查来实现该线程中列出的准修复。例如：

@SuppressWarnings("rawtypes")
@Override
public List getAllDepartments() {
    if (session == null) {
        System.out.println("****** CREATING SESSION ******");
        session = com.googlecode.s2hibernate.struts2.plugin.util.HibernateSessionFactory.getNewSession();
        if (!session.isOpen()) {
            throw new NullPointerException("Fix the code: session's not here");
        }
        transaction = session.beginTransaction();
    }

    if(!session.isOpen()) {
            System.out.println("****** REOPENING SESSION ******");

            session = session.getSessionFactory().openSession();
            //session = com.googlecode.s2hibernate.struts2.plugin.util.HibernateSessionFactory.getNewSession();
            transaction = session.beginTransaction();
    }

    return session.createQuery( "from Department" ).list();
}

第二个是基于上述线程添加以避免出现“org.hibernate.SessionException:Session is closed！”

这让我在某些时候通过了“java.lang.NullPointerException”和“org.hibernate.SessionException:会话已关闭！”但这是不一致的，如果我继续刷新页面，它最终会返回

这是这个新问题的堆栈跟踪（您可以看到我在上面的方法中的一些打印行）：

我可能只是错过了上面的会话签入了我的一个使用会话的方法。然而，在这一点上，这似乎不可能是答案，我要么做了一些非常错误的事情，要么在某个地方遗漏了一些东西

如果需要，我可以通过电子邮件向任何人发送此测试应用程序的WAR文件（使用Struts 2.1.6）。任何帮助都将不胜感激

多谢各位

PS：我确实先在插件支持论坛上发布了这篇文章，但没有得到任何回应，所以我希望so能够帮助我（code.google.com/p/full-hibernate-plugin-for-struts2/issues上的ISSUU#36）

似乎你被延迟加载的概念卡住了。为什么不将会话保持打开状态，直到您从实体加载所有项目或急切地加载所有项目时为止。
