Analysis:

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

In fact, in this case:

    <SelectID= "Getriskmember"Resultmap= "Baseresultmap" parametertype= "String">         <includerefID= "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:

  <SelectID= "Getriskmember"Resultmap= "Baseresultmap"ParameterType= "String">        <includerefID= "Selectmember"/>and safetylevel > 1 and stauts = 1<ifTest="_parameter! = null" >and username = #{username}</if>    </Select>
