实现

方式一：使用orderByDesc()方法

List<Employee> employeeList=employeeMapper.selectList(new EntityWrapper<Employee>()
    .eq("gender",1)
    .like("name", "霸")
    .orderDesc(Arrays.asList(new String[] {"age"}))
    );

方式二：使用orderBy()方法加last()方法

List<Employee> employeeList=employeeMapper.selectList(new EntityWrapper<Employee>()
    .eq("gender",1)
    .like("name", "霸")
    .orderBy("age")
    .last("desc")
    );

执行sql:

SELECT id AS id,`name`,email,gender,age FROM employee WHERE (gender = ? AND name LIKE ?) ORDER BY age desc

last()方法说明：

/**
     * <p>
     * 手动把sql拼接到最后(有sql注入的风险,请谨慎使用)
     * </p>
     *
     * @param limit
     * @return this
     */
    public Wrapper<T> last(String limit) {
        sql.LAST(limit);
        return this;
    }
