java - Hibernate 和 Spring 3 不保存

Question

我正在使用 hibernate 3 和 spring 3.0.7，我试图让我的代码将实体保存到数据库，但它就是不会这样做。

我已经尝试了所有方法，但似乎我做错了什么。

这是我使用 dao 方法的类

public boolean saveData(DataHolder holder,int type,Owners found){

    TempData temp = new TempData();
    temp.setDate(holder.getDate());
    temp.setTimestamp(new Timestamp(holder.getDate().getTime()));
    temp.setName(holder.getName());
    temp.setComId(holder.getCom().getComId());
    temp.setSymbol(holder.getCom().getSymbol());
    temp.setPercent(holder.getPercent());
    if(type == 1){
        temp.setOwnerId(found.getOwnerId());
        temp.setOwnerType(found.getType());
        tempDao.addTemp(temp);
        return true;
    }
    else{
        tempDao.addTemp(temp);
        return false;
    }
}

当然是一个用组件注释的bean

这是我的 dao 的 add 方法，但不起作用

public boolean addTemp(TempData entity){ try { getSession().save(entity); return true; } catch (Exception e) { e.printStackTrace(); return false; } }

这是我的实体

@Component public class TempData {

private int tempId;
private Date date;
private Timestamp timestamp;
private String name;
private String ownerType;
private Integer ownerId;
private String symbol;
private Integer comId;
private Double percent;

public int getTempId() {
    return tempId;
}

public void setTempId(int tempId) {
    this.tempId = tempId;
}

public Date getDate() {
    return date;
}

public void setDate(Date date) {
    this.date = date;
}

public Timestamp getTimestamp() {
    return timestamp;
}

public void setTimestamp(Timestamp timestamp) {
    this.timestamp = timestamp;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getOwnerType() {
    return ownerType;
}

public void setOwnerType(String ownerType) {
    this.ownerType = ownerType;
}

public Integer getOwnerId() {
    return ownerId;
}

public void setOwnerId(Integer ownerId) {
    this.ownerId = ownerId;
}

public String getSymbol() {
    return symbol;
}

public void setSymbol(String symbol) {
    this.symbol = symbol;
}

public Integer getComId() {
    return comId;
}

public void setComId(Integer comId) {
    this.comId = comId;
}

public Double getPercent() {
    return percent;
}

public void setPercent(Double percent) {
    this.percent = percent;
}

这是我的 hbm

这是 spring 配置的相关部分

<tx:advice id="tx" transaction-manager="transactionManager">
    <tx:attributes>
        <tx:method name="find*" propagation="REQUIRES_NEW"/>
        <tx:method name="add*" propagation="REQUIRES_NEW"/>
    </tx:attributes>
</tx:advice>

<aop:config>
    <aop:advisor advice-ref="tx" pointcut="execution(* *..AbstractDao.*(..))" />
    <aop:advisor advice-ref="tx" pointcut="execution(* *..TempDataDao.addTemp(..))" />
</aop:config>

事情是它完美地检索数据，但在保存数据时它不起作用，并且不同项目中的相同方法可以完美地工作，但在这里它们只是不工作，并且日志没有说明任何错误或某事，我什至尝试更改映射到错误表的名称，但仍然没有错误并完成事务，

我在这里缺少什么？

这就是我的调试器显示的内容，仅此而已

这就是我获得 session 的方式

public Session getSession(){
        return (this.factory.getCurrentSession()==null)?
                this.factory.getCurrentSession() : this.factory.openSession();
    }

Answer 1

该问题可能是由您获取 session 的方式引起的。您获得的 session 绝不会链接到 Spring 事务管理器，并且您使用它所做的事情是在 Spring 事务之外完成的。您应该在 spring 上下文中定义一个基于 Spring 的 session 工厂，并将其注入(inject)到您的 DAO 中，如 the documentation 中所述。 .
