Steps of integrated the JOOQ framework in the Spring Boot project (Steps to Integraate Jooq Framework in A Spring Boot Project)
Integrate the step of integrated the JOOQ framework in the Spring Boot project
JooQ is a popular Java database access framework that can simplify database operations.Integrating the JooQ framework in the Spring Boot project can make developers more easily interact with databases.This article will introduce how to integrate the JOOQ framework in the Spring Boot project.
Step 1: Add yoq dependencies
Add the following jooq dependencies to the pom.xml file of the Spring Boot project.
<dependency>
<groupId>org.jooq</groupId>
<artifactId>jooq</artifactId>
<version>3.15.0</version>
</dependency>
<dependency>
<groupId>org.jooq</groupId>
<artifactId>jooq-meta</artifactId>
<version>3.15.0</version>
</dependency>
<dependency>
<groupId>org.jooq</groupId>
<artifactId>jooq-codegen</artifactId>
<version>3.15.0</version>
</dependency>
Step 2: Configure the jooq code generator
JOOQ uses code generator to generate the physical class corresponding to the database table.In the Spring Boot project, we can configure the code generator by adding a configuration to the pom.xml file.
<build>
<plugins>
<plugin>
<groupId>org.jooq</groupId>
<artifactId>jooq-codegen-maven</artifactId>
<version>3.15.0</version>
<executions>
<execution>
<goals>
<goal>generate</goal>
</goals>
</execution>
</executions>
<configuration>
<jdbc>
<driver>com.mysql.jdbc.Driver</driver>
<url>jdbc:mysql://localhost:3306/mydatabase</url>
<user>username</user>
<password>password</password>
</jdbc>
<generator>
<database>
<name>org.jooq.meta.mysql.MySQLDatabase</name>
<includes>.*</includes>
<inputSchema>public</inputSchema>
</database>
<target>
<packageName>com.example.entity</packageName>
<directory>src/main/java</directory>
</target>
</generator>
</configuration>
</plugin>
</plugins>
</build>
In the above configuration, you need to replace the `url`,` user` and `Password` to your database connection information to ensure the correct configuration of the database driver.
Step 3: Generate physical class
Run the following Maven commands to generate the physical class.
mvn clean generate-sources
The generated physical class will be placed under the specified directory (in the configuration above is `com.example.entity`).
Step 4: Configure jooq and database connections
Add the following configuration to the Application.properties file of the Spring Boot project.
properties
spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase
spring.datasource.username=username
spring.datasource.password=password
# JOOQ Configuration
spring.jooq.sql-dialect=mysql
spring.jooq.sql-init-step=true
Make sure the `url`, username` and` password` are replaced with your database connection information.
Step 5: Create the jooq configuration class
In the Spring Boot project, we need to create a JooQ configuration class to configure the JooQ connection and execution.
@Configuration
public class JOOQConfiguration {
@Autowired
private DataSource dataSource;
@Bean
public DefaultDSLContext dslContext() {
ConnectionProvider connectionProvider = new DataSourceConnectionProvider(dataSource);
return new DefaultDSLContext(connectionProvider, SQLDialect.MYSQL);
}
}
In the above configuration class, we use the `DataSourceConnectionProvider` to associate the` DataSource` with the jooq's `dslContext`.
Step 6: Use jooq to perform database operations
Now you can use JooQ to perform database operations in the Spring Boot project.You can use jooq by automatically injected the `defaultdslContext` object.
@Repository
public class UserRepository {
@Autowired
private DSLContext dslContext;
public List<User> findAll() {
return dslContext.selectFrom(Tables.USER).fetchInto(User.class);
}
public void save(User user) {
dslContext.insertInto(Tables.USER, Tables.USER.NAME, Tables.USER.EMAIL)
.values(user.getName(), user.getEmail())
.execute();
}
}
In the above example, we use the `DSLContext` to perform a query and insertion operation.
The above is the step of integrating the JooQ framework in the Spring Boot project.Through these steps, you can easily use JOOQ to perform database operations in the Spring Boot project.
