自我复盘-20210820

近期在做一个双数据源同步的需求，项目主要采用springboot，通过JPA操作数据库，由于好久没玩hibernate了，凭借模糊的记忆加上Google大法，总算是有了一个大体上的熟系，现将开发过程中遇到的问题总结记录一下，弥补自己脑内存不足的问题，也希望对大家有所帮助。

1. 如果有条件尽量不要使用字符串

在拼接查询语句时，经常需要使用到表的列明，如代码中的missionId，建议常量化，方便代码调整改动，

Specification<MissionRuleRelation> specification = new Specification<>() {@Overridepublic Predicate toPredicate(Root<MissionRuleRelation> root, CriteriaQuery<?> query, CriteriaBuilder criteriaBuilder) {return criteriaBuilder.equal(root.get("missionId"), mission.getId());}
};

也可以引入hibernate的后处理器，会自动生成字段名的字符串常量

annotationProcessor('org.hibernate:hibernate-jpamodelgen:5.4.31.Final')

2. postgresql的建表语句

在项目中的建表语句，发现都有加上限定名，导致每次改表名的时候都忘记改相应的限定名，导致sql执行失败。其实默认情况下postgresql会自动生成相应格式的限定名。默认格式为"表名 _ 字段名 _ 约束简写",如“demo_name_key”
比如下面的唯一约束名‘demo_name_unique’

CREATE TABLE demo (id UUID PRIMARY KEY NOT NULL DEFAULT uuid_generate_v4(),"name" varchar(100) NOT NULL,CONSTRAINT demo_name_unique UNIQUE (name)
);

3. 全局跑测试无法查看日志

当测试失败时，借助**–info**及管道重定向方式，输出到日志文件方便查看及问题定位分析

./gradlew clean test --info > 1.log

4. 注意代理类

4.1. 定时任务

本项目采用的是SchedulerLock对分布式定时任务进行管控，在编写测试用例时直接调用了scheduleSyncData()方法，比如下面的代码就只能在10s内调用一次，从而导致有关的业务数据不是你希望的。所以最好不要直接测试scheduleSyncData()方法，可以测试doSyncData()。

@Scheduled(cron = "${sync-data:*/5 * * * * *}")
@SchedulerLock(name = "syncData", lockAtMostFor = "1h", lockAtLeastFor = "10s")
public void scheduleSyncData(){doSyncData();
}

从日志也可以看出，SchedulerLock执行前进行了判断

4.2. 声明式事物

这个大家应该都懂的，同一个类中的声明式事物最好不要相互调用，因为自调用是不走代理类的。所以要调用就要自己强行走代理了。

@Transactional(rollbackFor = Throwable.class)
public void sync(F from) {((AbstrackSyncWorker)AopContext.currentProxy()).doSync(from);fromRepository.updateSyncedToTrueById(from.getId());
}@Transactional(propagation = Propagation.REQUIRES_NEW, transactionManager = "rewardTransactionManager", rollbackFor = Throwable.class)
public void doSync(F from) {//
}

当然别忘记打开暴露代理的配置

@EnableAspectJAutoProxy(proxyTargetClass = true, exposeProxy = true)

5. jpa相关

5.1. 实体的继承

如果出现实体的继承，需要在父类上添加**@Inheritance**(strategy = InheritanceType.TABLE_PER_CLASS)（表的策略依实际情况设定），否则不会有父类的字段

5.2. 实体的映射关系

当存在例如@ManyToOne等关联关系时，lombok的@Data要注意tostring/hashcode造成死循环，可以借助如下两个注解进行排除

@EqualsAndHashCode.Exclude
@ToString.Exclude

lombok对于继承关系的tostring/hashcode/builder默认是不管父类的字段，如果需要调用父类的情况需要添加如下注解

@ToString(callSuper = true)
@EqualsAndHashCode(callSuper = true)
@SuperBuilder

5.3. 实体操作

hibernate使用@Version用于乐观锁，不能直接修改，出现以下异常，由于乐观锁version没有对上，导致操作数据库失败。

JpaRepository.saveAndFlush只是会执行相应的sql不会提交事物，所以并不会对当前entitymanager管理的entity体现例如@Version变化
JpaRepository.delete的删除不会立即执行，如果业务需要先删除后插入，则会异常，需要调用flush或者在delete方法上自己添加@Query(sql)
@Id的字段如果指定了@GeneratedValue会忽略手动赋值

6. error prone代码检查

error prone 对于标注了@Slf4j注解的，但从未使用过log的情况，会报类似IndexOutOfBoundsException的错，并不会具体指名哪里未使用过，所以报错了也很坑，完全不知道怎么就异常了。

7. idea工具莫名其妙

对于maven项目，平常本地都是直接运行main方法，但是对于gradle的项目可能会采用**./gradlew app:bootRun**方式运行，目前项目采用的就是gradle管理的，在使用@Lazy时就出现了空指针的情况。

// 1方式，两种方式都可以正常启动
// 2方式，main方法执行时,会在MeterRegistrygetMappedId()时，报filters的空指针异常
@Lazy // 1
@Bean
public MetricsRepositoryMethodInvocationListener metricsRepositoryMethodInvocationListener(
MetricsProperties metricsProperties, /**@Lazy 2*/MeterRegistry registry, RepositoryTagsProvider tagsProvider) {var properties = metricsProperties.getData().getRepository();return new MetricsRepositoryMethodInvocationListener(registry, tagsProvider, properties.getMetricName(), properties.getAutotime());
}

8.关于native query

8.1. uuid类型的映射

@Query(value = "select app.id as appId from app_source app ", nativeQuery = true)
List<IUu> findAppWithTrack();

调用此方法会报如下错误

主要原因是hibernate提供的PostgreSQL相关Dialect并未注册相应的数据类型，即有从java到RDB的映射registerColumnType( Types.OTHER, “uuid” );，但并没有类似的从RDB到java的映射registerHibernateType( Types.OTHER, StandardBasicTypes.UUID_CHAR.getName() );，所以解决办法有两种

提供扩展的Dialect

public class MyDialect extends PostgreSQL10Dialect {public MyDialect() {super();registerHibernateType( Types.OTHER, StandardBasicTypes.UUID_CHAR.getName() );}
}

类型转换

@Query(value = "select cast(app.id as varchar ) as appId from app_source app where app.name is null", nativeQuery = true)
List<IUu> findAppWithTrack();

使用SpEL转换或用其他方式转

public interface IUu {@Value("#{target.userId != null? T(java.util.UUID).fromString(target.userId) :null}")UUID getAppId();
}
