Analysis:

So what happens when "there is no getter for property named in ' Class Java.lang.String '" error?

In fact, in this case:

    <select id= "Getriskmember" resultmap= "Baseresultmap" parametertype= "String" >        <include refid= " Selectmember "/> and        safetylevel > 1 and        stauts = 1        <if test=" Username! = null "> and            username = #{username}         </if>    </select>

Note that it is the "there is no getter-named in ' Class Java.lang.String '" that occurs when the if test= is verified,

Instead of an error that occurs when and username = #{username}.

Workaround:

  <select id= "Getriskmember" resultmap= "Baseresultmap" parametertype= "String" >        <include refid= " Selectmember "/> and        safetylevel > 1 and        stauts = 1        <if test=" _parameter! = null ">            and Username = #{username}         </if>    </select>
