Adding dependency
<dependency>
<groupId>net.comze</groupId>
<artifactId>comze-orm</artifactId>
<version>3.3.2</version>
</dependency>
Sample Code
import net.comze.framework.orm.support.SqlMapDaoSupport;
public class SampleDao extends SqlMapDaoSupport {
private static final String SAMPLE_SQL_SELECT = "select `id`, `username` from `sample` where `id` > ? limit 1;";
public SampleEntity select(long id) {
return getSqlMapTemplate().queryForObject(SAMPLE_SQL_SELECT, SampleEntity.class, id);
}
}
import net.comze.framework.annotation.Attribute;
public class SampleEntity {
private Long id;
@Attribute(name = "username")
private String name;
// ... Aetter and setter
}
import javax.sql.DataSource;
import net.comze.framework.orm.datasource.DbcpDataSourceFactory;
public class Sample {
public void sample(long id) {
DataSource dataSource = new DbcpDataSourceFactory().getDataSource(); // load jdbc.properties
SampleDao sampleDao = new SampleDao();
sampleDao.setDataSource(dataSource);
SampleEntity sampleEntity = sampleDao.select(id);
// ...
}
}
Use @PropertiesEditor annotation
import net.comze.framework.annotation.Attribute;
import net.comze.framework.annotation.PropertyEditor;
public class SampleEntity {
private Long id;
@Attribute(name = "username")
private String name;
@PropertyEditor(className = "sample.JsonAddressEditor")
private Address address;
// ... Aetter and setter
}
public class Address {
private String state;
private String city;
private String street;
// ... Getter and setter
}
import java.beans.PropertyEditorSupport;
import com.google.gson.Gson;
public class JsonAddressEditor extends PropertyEditorSupport {
@Override
public Object getValue() {
return new Gson().fromJson(getAsText(), Address.class);
}
}
Use @LowerCaseWithUnderscores annotation
@LowerCaseWithUnderscores
public class SampleEntity {
// ...
}
public class SampleEntity {
private String firstName;
@LowerCaseWithUnderscores
private String lastName;
public String getFirstName() {
return firstName;
}
@LowerCaseWithUnderscores
public void setFirstName(String firstName) {
this.firstName = firstName;
}
// ...
}
Use @CaseSensitive(false) annotation
@CaseSensitive(false)
public class SampleEntity {
// ...
}
public class SampleEntity {
private String firstName;
@CaseSensitive(false)
private String lastName;
public String getFirstName() {
return firstName;
}
@CaseSensitive(false)
public void setFirstName(String firstName) {
this.firstName = firstName;
}
// ...
}
