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%）
