Question

简介

在阅读了一些博客并在jOOQ上观看了一些演示文稿之后，我非常高兴能够尝试逆向工程api并替换当前用于逆向工程数据库的hibernate工具。

基于Petri Kainulainen http://www.petrikainulainen.net/programming/jooq/using-jooq-with-spring-configuration/的示例配置和jOOQ https://github.com/jOOQ/jOOQ/tree/master/jOOQ-examples/jOOQ-spring-boot-example创始人的弹簧启动友好改编，我试图设置一个spring-boot-starter-jdbc，其目标是：从mysql数据库生成POJO（来自MySQL网站的sakila示例）。

使用mvn clean install运行程序和/或只是将其作为spring boot应用程序运行时，不会生成代码。标准弹簧启动应用程序运行，不显示错误和/或警告。

鉴于

</build>

鉴于我的主要配置类看起来像这样（所有bean代码都取自jOOQ-spring-boot-example）：

@Configuration
// not sure if I need this setting since I initialize it in the pom build
@PropertySource("classpath:application.properties") 
@Import({SpringTransactionProvider.class, ExceptionTranslator.class})
public class JooqSpringBootConfiguration {

    @Autowired
    private Environment env;    

    @Autowired
    private SpringTransactionProvider txp;

    @Autowired
    private ExceptionTranslator ext;

    @Bean(destroyMethod = "close")
    public DataSource dataSource() throws IllegalStateException, PropertyVetoException{
        ComboPooledDataSource dataSource = new ComboPooledDataSource();
        dataSource.setDriverClass(env.getRequiredProperty("db.driver"));
        dataSource.setJdbcUrl(env.getRequiredProperty("db.url"));
        dataSource.setUser(env.getRequiredProperty("db.username"));
        dataSource.setPassword("db.password");

        return dataSource;
    }

    @Bean
    public DataSourceTransactionManager transactionManager(DataSource dataSource) throws IllegalStateException, PropertyVetoException{
        return new DataSourceTransactionManager(dataSource());
    }

    @Bean
    public DSLContext dsl(org.jooq.Configuration config){
        return new DefaultDSLContext(config);
    }

    @Bean
    public ConnectionProvider connectionProvider(DataSource dataSource){
        return new DataSourceConnectionProvider(new TransactionAwareDataSourceProxy(dataSource));
    }

    @Bean
    public ExecuteListenerProvider executeListenerProvider(ExceptionTranslator exceptionTranslator){
        return new DefaultExecuteListenerProvider(ext);
    }

    @Bean
    public org.jooq.Configuration jooqConfig(ConnectionProvider connectionProvider, TransactionProvider transactionProvider, ExecuteListenerProvider executeListenerProvider){

        return new DefaultConfiguration()
                .derive(connectionProvider)
                .derive(txp)
                .derive(executeListenerProvider)
                .derive(SQLDialect.MYSQL);
    }

}

最后但并非最不重要的是source / main / resources目录中的application.properties文件：

#Database Configuration
db.driver=com.mysql.jdbc.Driver
db.url=jdbc:mysql://localhost:3306/SAKILA?useSSL=false
db.username=root
db.password=****

#jOOQ Configuration
jooq.generator.db.dialect=MYSQL

问题

鉴于上述配置，我错过了什么配置以及配置错误配置以启用代码生成（例如POJO）？

Answer 1

根据https://github.com/sivaprasadreddy/springboot-tutorials/tree/master/springboot-jooq-demo

中的示例找到问题的解决方案

我需要的只是一个配置良好的pom，不需要实际的Java代码。

只需使用通过配置文件反向清理安装，就可以生成我想要的代码。

pom（配置文件中的内容为id＆＃34;反向＆＃34;）：

        <directory>src/main/java</directory>
    </target>

  </configuration>
</plugin>

申请表：

package nl.sander.mieras.application;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
}
