When mybatis doing joint inquiry, suggesting that there is no getter setter methods.

In mybatis, if you want a id, associated with the primary key of another table, you must add a reference to the entity classes, namely private instance of a bean, or can not carry out a joint inquiry

 

<resultMap type="cn.taotao.bean.ZhouyiYao" id="WithIndexResultMap">
      <id column="id" jdbcType="INTEGER" property="id" />
    <result column="yaoId" jdbcType="INTEGER" property="yaoId" />
    <result column="yaoContent" jdbcType="VARCHAR" property="yaoContent" />
    <result column="yaoPic" jdbcType="VARCHAR" property="yaoPic"/> 
    < Result column = "the orderId" the jdbcType = "INTEGER" Property = "the orderId" > </ Result > 
    <-! Specifies the combined package the query field 64 Gua -> 
     < Association Property = "zhouyiIndex" the javaType = "cn.taotao.bean.ZhouyiIndex" > // lowercase zhouyiIndex. 
        < ID column = "yaoIndex" Property = "ID" /> 
        < Result column = "bname" Property = "name" /> 
    <
  

 

Error prompt, ZhouyiIndex no getter and setter methods, but the bean already have. The actual problem lies in

in association, property attributes, lowercase zhouyiIndex, I mistakenly written as uppercase ZhouyiIndex, he went to the capital of the constructor.
