Mybatis报错 There is no getter for property named xxxx

@Update({
            "<script>",
            "UPDATE service SET",
            "`gateway_port`=#{gatewayPort}, ",
            "`actor_url`=#{actorUrl}, ",
            "`backend_config`=#{backendConfig}, ",
            "`ace_config`=#{aceConfig}, ",
            "`service_url`=#{serviceUrl}, ",
            "`debug_port`=#{debugPort}, ",
            "`debug_url`=#{debugUrl}",
            "<if test='service.lsPort != null'>",
                    ",`ls_port` = #{lsPort}",
            "</if>",
            "WHERE id=#{id}",
            "</script>"
    })
    int updateResource(ServerPO service);

解决措施:
加上@Param注解

@Update({
            "<script>",
            "UPDATE service SET",
            "`gateway_port`=#{gatewayPort}, ",
            "`actor_url`=#{actorUrl}, ",
            "`backend_config`=#{backendConfig}, ",
            "`ace_config`=#{aceConfig}, ",
            "`service_url`=#{serviceUrl}, ",
            "`debug_port`=#{debugPort}, ",
            "`debug_url`=#{debugUrl}",
            "<if test='service.lsPort != null'>",
                    ",`ls_port` = #{lsPort}",
            "</if>",
            "WHERE id=#{id}",
            "</script>"
    })
    int updateResource(@Param("service") ServerPO service);
