    问题解决~了。。居然把get 和set改为首字母改为小写就可以。。为什么
      

  4.   

     大写的话，hibernate会找不到对应的函数给属性赋值或者取不到对应的属性值。
     
      

  5.   

    getName(),setName() get、set方法
      

  6.   


    不是我上网查的是比如属性是 private String name;  正常应该是  getName()这样但是这个问题我把它们的GET 和SET都改为  getname()就可以了~~~神马原因呢？
      

  7.   

    org.hibernate.property.BasicPropertyAccessorp 这个类有一个方法 getterMethod
    里面有个调用Introspector.decapitalize()；
    里面的源码是这样的
    public static String decapitalize(String name) {
    if (name == null || name.length() == 0) {
    return name;
    }
    if (name.length() > 1 && Character.isUpperCase(name.charAt(1))
    && Character.isUpperCase(name.charAt(0))) {
    return name;
    }
    char chars[] = name.toCharArray();
    chars[0] = Character.toLowerCase(chars[0]);
    return new String(chars);
    }
    你看下它的实现就可以了，如果属性的第一个字母和第二个字母是大写时会存在问题，我在以前的项目中也遇见过，所以避免在第一个字母和第二个字母大写
      

  8.   

    这个是java的一种机制我只能这么说。好比游戏规则。
      

  9.   

    正常情况下，譬如一个属性是name，setter方法是setName。
    这里你的命名有形如xPrice这样的，这样的命名的setter方法按上面的是setXPrice，但是这样是有问题的。你可以修改setter getter方法，或者是修改你的属性命名。
