分析：

那么什么情况下会发生“There is no getter for property named in ‘class java.lang.String’”错误呢？

其实是在这种情况下：

    <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>

注意看，是在if test=验证的时候发生的 “There is no getter for property named in ‘class java.lang.String’”，

而并非是and username = #{username} 的时候发生的错误。

解决办法：

  <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>
