在spring+hibernate框架的java项目开发过程中,经常会遇到这样的错误:
could not find a getter for ... in class ...
可能原因如下:
1.真的没有写getter方法(发生几率:1%)
2.*.hmb.xml文件中的属性名和pojo不一致(*.hbm.xml和*.java没衔接好,不一致),字段属性没有正确配置,比如,*.hmb.xml中*.java的地址要明确(明确指出引用包的完整路径);映射错误;有多个主键时,对生成的联合主键配置错误;拼写错误(包括多空格)等(发生几率:48%)
3.方法写错/方法名写错,要按照javabean的书写规范写啊,要不然打死也找不到哪儿错了(发生几率:50%)
这里提一下:get/set是不是不允许方法名中有连续两个大写字母,例如
public String getODPType(){
return this.oDPType;
}
public void setODPType(String oDPType){
this.oDPType = oDPType;
}
这样写它就会报错,报找不到getter for oDPType的错误,但下面这样写就可以了
public String odpType;
public String getOdpType(){
return this.odpType;
}
public void setOdpType(String odpType){
this.odpType = odpType;
}
4.其他不明原因(发生几率:1%)
