Spring-boot中使用nutz实践

已经用spring-boot启动一个新工程,能够运行,开始写业务代码。dao层繁杂的代码让人望而却步,急切找到一个方法来简化它。

网上找nutz在spring-boot中使用的相关资料,比较匮乏,自己边尝试边整理一下。官方demo

下面给出相关配置,Dao层一个业务实例,以及junit本地测试的实例。

maven

<dependency>
    <groupId>org.nutz</groupId>
    <artifactId>nutz-plugins-spring-boot-starter</artifactId>
    <version>${version}</version>
</dependency>

gradle

compile group: 'org.nutz', name: 'nutz-plugins-spring-boot-starter', version: '1.r.63'

代码实例

1. 业务Dao接口(Resource是自定义的业务数据)

public interface ResourceDao {

    void insertResource(Resource resource);

    List<Resource> listResources();
}

2. 业务Dao实现

import org.nutz.dao.Cnd;
import org.nutz.dao.Condition;
import org.nutz.dao.Dao;
import org.nutz.dao.impl.NutDao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import java.util.List;
@Repository
public class ResourceDaoImpl extends NutDao implements ResourceDao {

    @Autowired
    private Dao dao;

    @Override
    public void insertResource(Resource resource) {
        dao.insert(resource);
    }

    @Override
    public List<outfox.ynote.data.Resource> listResources() {
        Condition condition = Cnd.orderBy().desc("id");
        return dao.query(Resource.class, condition);
    }
}

3. 配置文件

#---------jdbc with MySQL---------#
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/XXXX
spring.datasource.username=XXXX
spring.datasource.password=XXXX

4. 本地测试和数据库连接

import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;

public class TestResourceDao extends CommonTest{

    @Autowired
    public ResourceDao resourceDao;

    @Test
    public void test() {
        Resource resource = new Resource();
        // add some resource properties

        resourceDao.insertResource(resource);
        List<Resource> resourceList = resourceDao.listResources();
        for (Resource temp : resourceList) {
            System.out.println(temp.toString());
        }
    }
}

@RunWith(SpringRunner.class)
@SpringBootTest
@ActiveProfiles("test")
public class CommonTest {
    @Autowired
    @Qualifier("jdbcTemplate")
    protected JdbcTemplate jdbcTemplate;
}

@Configuration
@EnableTransactionManagement
public class DBConfig {
    @Bean(name = "jdbcTemplate")
    public JdbcTemplate jdbcTemplate(
            @Qualifier("dataSource") DataSource dataSource) {
        return new JdbcTemplate(dataSource);
    }
}
