mybatis学习：mybatis注解开发一对多

实体类User：

 public class User implements Serializable {

     private Integer id;
     private String username;
     private Date birthday;
     private String sex;
     private String address;

     //一对多关系映射：一个用户对应多个账户
     private List<Account> accounts;

     public List<Account> getAccounts() {
         return accounts;
     }

     public void setAccounts(List<Account> accounts) {
         this.accounts = accounts;
     }

     public Integer getId() {
         return id;
     }

     public void setId(Integer id) {
         this.id = id;
     }

     public String getUsername() {
         return username;
     }

     public void setUsername(String username) {
         this.username = username;
     }

     public Date getBirthday() {
         return birthday;
     }

     public void setBirthday(Date birthday) {
         this.birthday = birthday;
     }

     public String getSex() {
         return sex;
     }

     public void setSex(String sex) {
         this.sex = sex;
     }

     public String getAddress() {
         return address;
     }

     public void setAddress(String address) {
         this.address = address;
     }

     @Override
     public String toString() {
         return "User{" +
                 "id=" + id +
                 ", username='" + username + '\'' +
                 ", birthday=" + birthday +
                 ", sex='" + sex + '\'' +
                 ", address='" + address + '\'' +
                 '}';
     }
 }

dao层：

IUserDao：

     @Select("select * from user")
     @Results(id = "userMap",value = {
             @Result(id = true,column = "id",property = "id"),
             @Result(column = "username",property = "username"),
             @Result(column = "address",property = "address"),
             @Result(column = "sex",property = "sex"),
             @Result(column = "birthday",property = "birthday"),
             @Result(property = "accounts",column = "id",many = @Many(select = "cn.flypig666.dao.IAccountDao.findAccountByUid",
                     fetchType = FetchType.EAGER))
     })
     List<User> findAll();

IAccountDao：

 /**
     * 根据用户id查询账户信息
     * @param userId
     * @return
     */
    @Select("select * from account where uid = #{uid}")
    List<Account> findAccountByUid(Integer userId);
}
