Mybatis注解方式@Insert的用法

@Insert({"insert into user(name, create_time) values(#{name}, #{createTime, jdbcType=TIMESTAMP})"})
int add(User user);

@Insert({"insert into user(name, create_time) values(#{name}, #{createTime, jdbcType=TIMESTAMP})" })
@Options(useGeneratedKeys = true, keyProperty = "id")
int add2(Useruser);

@Insert({"insert into user(name, create_time) values(#{name}, #{createTime, jdbcType=TIMESTAMP})" })
@SelectKey(statement = "SELECT LAST_INSERT_ID()", keyProperty = "id", resultType = Long.class, before = false)
int add3(User user);

    private Integer sysRoleFunctionId;
    private String operation;
    private Integer sysRoleId;

    @Insert( "<script>"  +
                "insert into sys_role_function (sys_role_function_id,operation,sys_role_id)  VALUES " +
                "<foreach collection='list' item='item' index='index' separator=','> " +
                "(#{item.sysRoleFunctionId},#{item.operation},#{item.sysRoleId}) " +
                "</foreach>" +
