可能原因如下：

1.真的沒有寫getter方法（發生幾率：1%）

2.*.hmb.xml文件中的屬性名和pojo不一致（*.hbm.xml和*.java沒銜接好，不一致），字段屬性沒有正確配置，比如，*.hmb.xml中*.java的地址要明確（明確指出引用包的完整路徑）；映射錯誤；有多個主鍵時，對生成的聯合主鍵配置錯誤；拼寫錯誤（包括多空格）等（發生幾率：48%）

3.方法寫錯/方法名寫錯，要按照javabean的書寫規范寫啊，要不然打死也找不到哪兒錯了（發生幾率：50%）

這裡提一下：get/set是不是不允許方法名中有連續兩個大寫字母，例如

public String getODPType(){

        return this.oDPType;

}

public void setODPType(String      oDPType){

this.oDPType = oDPType;

}

這樣寫它就會報錯，報找不到getter for oDPType的錯誤，但下面這樣寫就可以了

public String odpType;

public String getOdpType(){

        return this.odpType;

}

public void setOdpType(String      odpType){

this.odpType = odpType;

}

4.其他不明原因（發生幾率：1%）
