生成代码
运行 mvn clean install -Djooq 命令生成代码,点击maven里面的按钮也能生成,如下图:
执行命令后会生成以下几个类:
pojos下面的类是我们会用到的实体类,而tables文件夹下面的实体类是利用DSL查询时拼接sql的表名、字段名
service层部分代码示例
ys.manufacture.generate.tables.IdeUserTest USER = ys.manufacture.generate.tables.IdeUserTest.IDE_USER_TEST;
/**
* 通过主键查询
*
* @param user_number
* @return
*/
public IdeUserTest getByJooqFindId(String user_number) {
//用DSL
DSLContext create = DSL.using(dataSource,SQLDialect.MYSQL);
List ideUserTests = create.select(USER.USER_AGE,USER.USER_NAME)
.from(USER).where(USER.USER_NUMBER.eq(user_number)).fetchInto(IdeUserTest.class);
}
/**
* 通过jooq新增demo
* @param inputBean
* @return
*/
public UserTestViewOutputBean addByJooq(UserTestViewInputBean inputBean) {
String meacon = genNoService.getNo("userId", commonService.getCurrentDateTime().jaDateValue());
LocalDateTime localDateTime = Instant.ofEpochMilli(JaDate.today().dateValue().getTime()).atZone(ZoneId.systemDefault()).toLocalDateTime();
//DSL方法
DSLContext create = DSL.using(dataSource,SQLDialect.MYSQL);
int execute = create.insertInto(USER)
.columns(USER.USER_NUMBER, USER.USER_NAME, USER.USER_AGE, USER.USER_DATE, USER.USER_TEL)
.values(meacon, inputBean.getUser_name(), inputBean.getUser_age(), localDateTime, inputBean.getUser_tel())
.execute();
return new UserTestViewOutputBean();
}
/**
* 删除
* @param inputBean
* @return
*/
public UserTestViewOutputBean delByJooq(UserTestViewInputBean inputBean) {
//dao 方法
dao.deleteById(inputBean.getUser_number());
return new UserTestViewOutputBean();
}
/**
* 修改
* @param inputBean
* @return
*/
public UserTestViewOutputBean editByJooq(UserTestViewInputBean inputBean) {
//DSL方法
DSLContext create = DSL.using(dataSource, SQLDialect.MYSQL);
int execute = create.update(USER)
.set(USER.USER_NAME, inputBean.getUser_name())
.where(USER.USER_NUMBER.eq(inputBean.getUser_number()))
.execute();
return new UserTestViewOutputBean();
}
@Autowired
DSLContext dslContext;
/**
*
* 事务测试
* @param inputBean
* @return
* @throws SqlParserException
*/
public UserTestViewOutputBean transactionJooq(UserTestViewInputBean inputBean)throws SqlParserException {
DSL.using(dataSource,SQLDialect.MYSQL).transaction(new TransactionalRunnable() {
@Override
public void run(Configuration configuration) throws Exception {
DSLContext create = DSL.using(configuration);
int execute = create.update(USER)
.set(USER.USER_AGE, inputBean.getUser_age())
.where(USER.USER_NUMBER.eq(inputBean.getUser_number()))
.execute();
int execute1 = dslContext.deleteFrom(USER).where(USER.USER_AGE.eq(inputBean.getUser_age())).execute();
}
});
return new UserTestViewOutputBean();
}
上面查询语句代码可读性很强,实现了java代码代替了sql语句。除了用这种方式是查询之外,还可以利用自动生成的dao层,
不过在使用dao时,需先调用它的构造方法注入,不能直接用@Autowired或@Resource注解注入,代码如下图:
@Autowired
DataSource dataSource;
private IdeUserTestDao dao;
@PostConstruct//表示在UserServiceImpl构造完成之后执行
private void createDao() {
// DSL上下文是所有数据库操作的入口,意思就是要用jooq干任何事都要先实例化这个DSLContext
DSLContext dsl = DSL.using(dataSource, SQLDialect.MYSQL);
dao = new IdeUserTestDao(dsl.configuration());
}
ys.manufacture.generate.tables.IdeUserTest USER = ys.manufacture.generate.tables.IdeUserTest.IDE_USER_TEST;
/**
* 通过主键查询
*
* @param user_number
* @return
*/
public IdeUserTest getByJooqFindId(String user_number) {
//用dao方法
IdeUserTest userTest = dao.findById(user_number);
return userTest;
}
/**
* 通过jooq新增demo
* @param inputBean
* @return
*/
public UserTestViewOutputBean addByJooq(UserTestViewInputBean inputBean) {
String meacon = genNoService.getNo("userId", commonService.getCurrentDateTime().jaDateValue());
LocalDateTime localDateTime = Instant.ofEpochMilli(JaDate.today().dateValue().getTime()).atZone(ZoneId.systemDefault()).toLocalDateTime();
//dao方法
IdeUserTest userTest = new IdeUserTest();
userTest.setUserNumber(meacon);
userTest.setUserTel(inputBean.getUser_tel());
userTest.setUserName(inputBean.getUser_name());
userTest.setUserAge(inputBean.getUser_age());
userTest.setUserDate(localDateTime);
dao.insert(userTest);
return new UserTestViewOutputBean();
}
/**
* 删除
* @param inputBean
* @return
*/
public UserTestViewOutputBean delByJooq(UserTestViewInputBean inputBean) {
//dao 方法
dao.deleteById(inputBean.getUser_number());
return new UserTestViewOutputBean();
}
/**
* 修改
* @param inputBean
* @return
*/
public UserTestViewOutputBean editByJooq(UserTestViewInputBean inputBean) {
//dao 方法
IdeUserTest userTest = new IdeUserTest();
userTest.setUserNumber(inputBean.getUser_number());
userTest.setUserTel(inputBean.getUser_tel());
userTest.setUserName(inputBean.getUser_name());
userTest.setUserAge(inputBean.getUser_age());
dao.update(userTest);
return new UserTestViewOutputBean();
}
事务
可以直接在数据库中发出特定于供应商的COMMIT,ROLLBACK和其他语句;
可以在JDBC驱动程序上调用JDBC的Connection.commit(),Connection.rollback()和其他方法;
可以使用第三方事务管理库,例如Spring TX(@Transactional);
可以从容器中使用符合JTA的Java EE事务管理器;
