1. javax.el.PropertyNotFoundException 一种可能，你太累了，写错了表达式，比如
看看 items=”uAddrsList” , 羞羞
解决方案：去休息一下
去休息一下
2. javax.el.PropertyNotFoundException 第二种请款可能是没有 model 对应的 getter、setter；其次，还有要注意在eclipse 里面自动生成的 boolean 的 getter、setter 在 EL/或者一些sql映射的时候都不起作用！！！
原来的model中的域和方法如下：
解决方法：添加有效形式的getter/setter

原来的model中的域和方法如下：
private boolean isDefault;
......
public boolean isDefault() {
return isDefault;
}
public void setDefault(boolean isDefault) {
this.isDefault = isDefault;
}解决方法：添加有效形式的getter/setter
//addOn for for sql mapping and EL
public boolean getIsDefault(){
return isDefault;
}
public void setIsDefault(boolean isDefault){
this.isDefault = isDefault;
}
