Spring5、springboot2近況

  • spring5

    最大的亮點(diǎn)是 Spring webflux。Spring webflux 是一個(gè)新的非堵塞函數(shù)式 Reactive Web 框架，可以用來(lái)建立異步的，非阻塞，事件驅(qū)動(dòng)的服務(wù)，并且擴(kuò)展性非常好。

  • springboot

    集成了大量常用的第三方庫(kù)配置（例如Jackson, JDBC, Mongo, Redis, Mail等等），Spring Boot應(yīng)用中這些第三方庫(kù)幾乎可以零配置的開箱即用（out-of-the-box），大部分的Spring Boot應(yīng)用都只需要非常少量的配置代碼，開發(fā)者能夠更加專注于業(yè)務(wù)邏輯。

</configuration>
  • 修改DAO注解
@Mapper
public interface UserDao {

    @Select("SELECT id, name, gender, createTime FROM User where id=#{id}")
    public User findById(Long id);

}
  • 初始化數(shù)據(jù)庫(kù)
CREATE TABLE `User` (
  `id` bigint(20) NOT NULL,
  `name` varchar(20) DEFAULT NULL,
  `gender` varchar(20) DEFAULT NULL,
  `createTime` datetime DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
  • CRUD
@Insert("INSERT INTO User(id,name,gender,createTime) VALUES(#{id}, #{name}, #{gender}, #{createTime})")
void insert(User user);

@Delete("DELETE FROM User WHERE id = #{id}")
void delete(Long id);

@Update("UPDATE User SET name=#{name},gender=#{gender},createTime=#{createTime} WHERE id =#{id}")
void update(User user);

@Select("SELECT id, name, gender, createTime FROM User")
List<User> findAll();

@Service

    public void remove(Long id){
        dao.delete(id);
    }

    public List<User> findAll(){
        return dao.findAll();
    }

}
  • 添加單元測(cè)試依賴
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
</dependency>
  • 編寫測(cè)試類
@RunWith(SpringRunner.class)

        o = service.findById(o.getId());
        Assert.assertNull(o);

    }
    
}

  • 引入主鍵生成器 IdGenerator

  • XML方式實(shí)現(xiàn)DAO接口

List<User> findByName(String name);

  • 添加mapper文件（文件名需要和接口名一致）
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

    <select id="findByName" resultMap="BaseResultMap" >
        SELECT <include refid="Base_Column_List" /> FROM User WHERE name = #{name}
    </select>

</mapper>
  • 添加logback.xml配置,查看sql
<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">

    <!--定義日志文件的存儲(chǔ)地址 勿在 LogBack 的配置中使用相對(duì)路徑-->

如何寫一個(gè)對(duì)用戶友好的接口

  • 問(wèn)題

    用戶有哪些，測(cè)試人員、開發(fā)人員、瀏覽器、調(diào)試工具、客戶端程序等

    開發(fā)人員拿到?jīng)]有統(tǒng)一格式的數(shù)據(jù)，沒辦法分層處理

    為了方便框架解析、分層控制，有必要規(guī)范輸入輸出格式

  • 事例 getUser
{
    "id": 4354523,
    "name":"張三"
}

{
    "errorCode":-10000,
    "message":"未登錄"
}

{
    "bizCode":-1,
    "message":"所查用戶不存在"
}

{
    "code": 1,
    "message":""，
    "data"：{
        "id": 4354523,
        "name":"張三"
    }
}

{
    "code": -10000,
    "message":"未登錄"，
    "data"：{
    }
}

{
    "code": -1,
    "message":"所查用戶不存在"，
    "data"：{
    }
}
  • 引入ViewData
public class ViewData<T> implements Serializable{

    private static final long serialVersionUID = 7408790903212368997L;

    private Integer code = 1;

    private String message;

    private T data;

    public ViewData(){}

    public ViewData(T obj) {
        this.data = obj;
    }

    public ViewData(Integer code, String message) {
        this.code = code;
        this.message = message;
    }

    public ViewData(Integer code, String message, T obj) {
        this.code = code;
        this.message = message;
        this.data = obj;
    }

    public static <T> ViewData<T> ok() {
        return new ViewData<>();
    }

    public static <T> ViewData<T> ok(T obj) {
        return new ViewData<>(obj);
    }

    public static <T> ViewData<T> error(String msg) {
        return new ViewData<>(-1, msg);
    }

    public static <T> ViewData<T> error(Integer code, String msg) {
        return new ViewData<>(code, msg);
    }

}
  • 對(duì)輸出數(shù)據(jù)進(jìn)行格式化
package com.caad.springboot.test.api.resp;

public class UserResp {

    private Long id;
    private String username;
    private Date createTime;
    private GenderType gender;

}

@RequestMapping(value = "/find/{id}")
public ViewData<UserResp> find(@PathVariable("id") Long id) {
    User user = userService.findById(id);
    UserResp resp = new UserResp();
    resp.setCreateTime(user.getCreateTime());
    resp.setGender(user.getGender());
    resp.setUsername(user.getName());
    resp.setId(user.getId());
    return ViewData.ok(resp);
}
  • 使用@RequestBody對(duì)輸入?yún)?shù)格式化
package com.caad.springboot.test.api.requ;

public class UserRequ {

    private Long id;
    private String name;
    private String gender;

    public UserRequ() { }

    public UserRequ(Long id, String name, String gender) {
        this.id = id;
        this.name = name;
        this.gender = gender;
    }

}


@RequestMapping(value = "/update")
public ViewData<User> update(@RequestBody UserRequ userRequ) {
    User user = userService.findById(userRequ.getId());
    user.setName(userRequ.getName());
    user.setGender(GenderType.valueOf(userRequ.getGender()));
    userService.save(user);
    return ViewData.ok(user);
}

http://localhost:8080/user/update
{
    "id":1,
    "name":"hi boy",
    "gender":"MALE"
}
  • 自定義數(shù)據(jù)轉(zhuǎn)換
@Component
public class JsonDataSerializer extends JsonSerializer<Object> {

    @Override

        if(o==null) return;
        if(o instanceof Long){
            Long data = (Long) o;
            jsonGenerator.writeString(data.toString());
        } if(o instanceof Date){
            Date date = (Date) o;
            jsonGenerator.writeString(date.getTime() + "");
        }
    }

}

要裝換的字段使用 @JsonSerialize(using = JsonDataSerializer.class)

處理空字段 @JsonInclude(Include.NON_NULL)

  • 使用map傳參
@RequestMapping(value = "/findByName")
public ViewData<List<User>> findByName(@RequestBody Map<String,String> params) {
    List<User> list = userService.findByName(params.get("name"));
    return ViewData.ok(list);
}

http://localhost:8080/user/findByName
{
    "name":"ZHANG"
}
  • 異常處理
public User addUser(User user) throws DataDuplicateException {
    List<User> list = dao.findByName(user.getName());
    if(list!=null && list.size()>0){
        throw new DataDuplicateException("用戶已經(jīng)存在");
    }
    return this.save(user);
}

package com.caad.springboot.test.common.exception;

public class DataDuplicateException extends RuntimeException {

    public DataDuplicateException() {
        super();
    }

    public DataDuplicateException(String message) {
        super(message);
    }

}

@RequestMapping(value = "/add")
public ViewData<User> add(@RequestBody UserRequ userRequ) {
    if(userRequ.getName()==null) return ViewData.error("用戶名未填寫");
    if(userRequ.getGender()==null) return ViewData.error("性別未填寫");
    User user = new User();
    user.setCreateTime(new Date());
    user.setGender(GenderType.valueOf(userRequ.getGender()));
    user.setName(userRequ.getName());
    try {
        userService.addUser(user);
    }catch (DataDuplicateException e){
        return ViewData.error(-1, e.getMessage());
    }
    return ViewData.ok(user);
}

http://localhost:8080/user/add
{
    "name":"testsa2",
    "gender":"MALE"
}
  • 刪除User接口
@RequestMapping(value = "/remove/{id}")
public ViewData remove(@PathVariable("id") Long id) {
    User user = new User();
    user.setId(id);
    user.setCreateTime(new Date());
    user.setGender(GenderType.UNKNOW);
    user.setName("test");
    userService.remove(user.getId());
    return ViewData.ok();
}

測(cè)試 http://localhost:8080/user/remove/1

抽取抽象邏輯，封裝通用代碼，控制框架行為

  • 抽取父類
public abstract class GenericService<T extends BaseEntity> {

    @Autowired
    LongIdGenerator idGenerator;

    protected abstract GenericDao<T> getDao();

    public T findById(Long id) {
        return getDao().findById(id);
    }

    public T save(T entity){
        if(entity==null) return null;
        if(entity.getId()==null){
            entity.setId(idGenerator.generate());
            getDao().insert(entity);
        }else {
            getDao().update(entity);
        }
        return entity;
    }

    public void remove(Long id){
        getDao().delete(id);
    }

    public List<T> findAll(){
        return getDao().findAll();
    }

}


public interface GenericDao<T extends BaseEntity> {

    public T findById(Long id);

    void insert(T entity);

    void delete(Long id);

    void update(T entity);

    List<T> findAll();

}

public abstract class BaseEntity {

    public abstract Long getId();

    public abstract void setId(Long id);

}
  • 使用泛型主鍵
public abstract class BaseEntity<PK extends Serializable> {

    public abstract PK getId();

    public abstract void setId(PK id);

}


public interface GenericDao<T extends BaseEntity, PK extends Serializable> {

    public T findById(PK id);

    void insert(T entity);

    void delete(PK id);

    void update(T entity);

    List<T> findAll();

}

public interface GenericDao<T extends BaseEntity, PK extends Serializable> {

    public T findById(PK id);

    void insert(T entity);

    void delete(PK id);

    void update(T entity);

    List<T> findAll();

}
