摘要：在這個(gè)例子中，我們將整合但您也可以使用其他連接池，如，，等。作為構(gòu)建和執(zhí)行。
jOOQ和Spring很容易整合。 在這個(gè)例子中，我們將整合：
Alibaba Druid（但您也可以使用其他連接池，如BoneCP，C3P0，DBCP等）。
Spring TX作為事物管理library。
jOOQ作為SQL構(gòu)建和執(zhí)行l(wèi)ibrary。
一、準(zhǔn)備數(shù)據(jù)庫(kù)
DROP TABLE IF EXISTS `author`;
CREATE TABLE `author` (
`id` int(11) NOT NULL,
`first_name` varchar(50) DEFAULT NULL,
`last_name` varchar(50) NOT NULL,
`date_of_birth` date DEFAULT NULL,
`year_of_birth` int(11) DEFAULT NULL,
`distinguished` int(1) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
DROP TABLE IF EXISTS `book`;
CREATE TABLE `book` (
`id` int(11) NOT NULL,
`author_id` int(11) NOT NULL,
`title` varchar(400) NOT NULL,
`published_in` int(11) NOT NULL,
`language_id` int(11) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
DROP TABLE IF EXISTS `book_store`;
CREATE TABLE `book_store` (
`name` varchar(400) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
DROP TABLE IF EXISTS `book_to_book_store`;
CREATE TABLE `book_to_book_store` (
`name` varchar(400) NOT NULL,
`book_id` int(11) NOT NULL,
`stock` int(11) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
DROP TABLE IF EXISTS `language`;
CREATE TABLE `language` (
`id` int(11) NOT NULL,
`cd` char(2) NOT NULL,
`description` varchar(50) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
ALTER TABLE `author`
ADD PRIMARY KEY (`id`);
ALTER TABLE `book`
ADD PRIMARY KEY (`id`),
ADD KEY `fk_book_author` (`author_id`),
ADD KEY `fk_book_language` (`language_id`);
ALTER TABLE `book_store`
ADD UNIQUE KEY `name` (`name`);
ALTER TABLE `book_to_book_store`
ADD PRIMARY KEY (`name`,`book_id`),
ADD KEY `fk_b2bs_book` (`book_id`);
ALTER TABLE `language`
ADD PRIMARY KEY (`id`);
二、添加所需的Maven依賴項(xiàng)
在這個(gè)例子中，我們將創(chuàng)建以下Maven依賴項(xiàng)：

三、Spring配置文件
Spring Configuration
MYSQL
四、Spring Test + JUnit集成測(cè)試
查詢測(cè)試：
package test.generated.service;
import static java.util.Arrays.asList;
import static org.jooq.impl.DSL.countDistinct;
import static org.junit.Assert.assertEquals;
import static test.generated.Tables.*;
import org.jooq.DSLContext;
import org.jooq.Record3;
import org.jooq.Result;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import test.generated.tables.Author;
import test.generated.tables.Book;
import test.generated.tables.BookStore;
import test.generated.tables.BookToBookStore;
import test.generated.tables.records.BookRecord;
/**
* @author Lukas Eder
*/
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/jooq-spring.xml"})
public class QueryTest {
@Autowired
DSLContext create;
@Test
public void testJoin() throws Exception {
// All of these tables were generated by jOOQ"s Maven plugin
Book b = BOOK.as("b");
Author a = AUTHOR.as("a");
BookStore s = BOOK_STORE.as("s");
BookToBookStore t = BOOK_TO_BOOK_STORE.as("t");
Result> result =
create.select(a.FIRST_NAME, a.LAST_NAME, countDistinct(s.NAME))
.from(a)
.join(b).on(b.AUTHOR_ID.eq(a.ID))
.join(t).on(t.BOOK_ID.eq(b.ID))
.join(s).on(t.NAME.eq(s.NAME))
.groupBy(a.FIRST_NAME, a.LAST_NAME)
.orderBy(countDistinct(s.NAME).desc())
.fetch();
assertEquals(2, result.size());
assertEquals("Paulo", result.getValue(0, a.FIRST_NAME));
assertEquals("George", result.getValue(1, a.FIRST_NAME));
assertEquals("Coelho", result.getValue(0, a.LAST_NAME));
assertEquals("Orwell", result.getValue(1, a.LAST_NAME));
assertEquals(Integer.valueOf(3), result.getValue(0, countDistinct(s.NAME)));
assertEquals(Integer.valueOf(2), result.getValue(1, countDistinct(s.NAME)));
}
}
數(shù)據(jù)插入，使用Spring的TransactionManager來(lái)顯式處理事務(wù)：
package test.generated.service;
import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertTrue;
import static test.generated.Tables.BOOK;
import java.util.concurrent.atomic.AtomicBoolean;
import org.jooq.DSLContext;
import org.junit.After;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.dao.DataAccessException;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.transaction.TransactionConfiguration;
import org.springframework.transaction.TransactionStatus;
import org.springframework.transaction.support.DefaultTransactionDefinition;
/**
* @author Petri Kainulainen
* @author Lukas Eder
*
* @see http://www.petrikainulainen.net/programming/jooq/using-jooq-with-spring-configuration/
*/
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/jooq-spring.xml"})
@TransactionConfiguration(transactionManager="transactionManager")
public class TransactionTest {
@Autowired DSLContext dsl;
@Autowired DataSourceTransactionManager txMgr;
@Test
public void testDelBooks() {
// Delete all books that were created in any test
dsl.delete(BOOK).where(BOOK.ID.gt(4)).execute();
}
@Test
public void testAddBooks() {
TransactionStatus tx = txMgr.getTransaction(new DefaultTransactionDefinition());
for (int i = 1; i <= 6; i++)
dsl.insertInto(BOOK)
.set(BOOK.ID, i)
.set(BOOK.PUBLISHED_IN, 1)
.set(BOOK.LANGUAGE_ID, 1)
.set(BOOK.AUTHOR_ID, 1)
.set(BOOK.TITLE, "Book " + i)
.execute();
txMgr.commit(tx);
}
@Test
public void testExplicitTransactions() {
boolean rollback = false;
TransactionStatus tx = txMgr.getTransaction(new DefaultTransactionDefinition());
try {
// This is a "bug". The same book is created twice, resulting in a
// constraint violation exception
for (int i = 7; i <=9; i++)
dsl.insertInto(BOOK)
.set(BOOK.ID, i)
.set(BOOK.AUTHOR_ID, 1)
.set(BOOK.TITLE, "Book " + i)
.execute();
Assert.fail();
}
// Upon the constraint violation, we explicitly roll back the transaction.
catch (DataAccessException e) {
txMgr.rollback(tx);
rollback = true;
}
assertEquals(4, dsl.fetchCount(BOOK));
assertTrue(rollback);
}
}
