aridpojo简化Spring配置

最近在TSS上看到aridpojo框架（code.google.com/p/aridpojos/），能够自动创建spring的bean定义（Chris Richardson's Spring library to autocreate bean definitions）。忍不住试了下。
创建一个Dao接口：
package test.dao;

import test.TestBean;

public interface IDao {
public TestBean add(TestBean bean);
public TestBean delete(TestBean bean);

}
写一个简单的Dao实现类，仅仅输出一些文字：
package test.dao;

import test.TestBean;

public class PlainDaoImpl implements IDao {

@Override
public TestBean add(TestBean bean) {
// TODO Auto-generated method stub
System.out.println("dao add method...");
return bean;
}

@Override
public TestBean delete(TestBean bean) {
// TODO Auto-generated method stub
System.out.println("dao delete method...");
return bean;
}

}
再写一个服务类接口：
package test.service;

import test.TestBean;

public interface IService {
public TestBean add(TestBean bean);
public TestBean delete(TestBean bean);
}
写一个简单的实现类，调用Dao实现类中的相应方法：
package test.service;

import test.TestBean;
import test.dao.IDao;

public class PlainServiceImpl implements IService{
private IDao plainDao=null;

@Override
public TestBean add(TestBean bean) {
// TODO Auto-generated method stub
System.out.println("service add method...");
this.plainDao.add(bean);
return null;
}

@Override
public TestBean delete(TestBean bean) {
// TODO Auto-generated method stub
System.out.println("service delete method...");
this.plainDao.delete(bean);
return null;
}

public void setPlainDao(IDao plainDao) {
this.plainDao = plainDao;
}


}
写一个简单的javabean：
package test;

public class TestBean {
private int id;
private String name;

public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}

}
配置文件testApplicationContext.xml，这是重点：
<beans xmlns="http://www.springframework.org/schema/beans"><arid:define-beans package="test.service"><arid:define-beans package="test.dao"><beans xmlns="http://www.springframework.org/schema/beans"><arid:define-beans package="test.service"><arid:define-beans package="test.dao">
</arid:define-beans>《?xml version="1.0" encoding="UTF-8"?》
《beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:arid="http://chrisrichardson.net/schema/arid"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://chrisrichardson.net/schema/arid http://chrisrichardson.net/schema/arid.xsd"
default-autowire="byName"》

《arid:define-beans package="test.service"
autowire="byType" /》
《arid:define-beans package="test.dao"
autowire="byType" /》
《/beans》
</arid:define-beans>
首先引入：http://chrisrichardson.net/schema/arid http://chrisrichardson.net/schema/arid.xsd。然后使用arid命名空间配置。package属性设置需要自动创建bean定义的包名；autowire属性设置按何种方式自动设置bean直接的引用关系，这个属性和spring本身的autowire的含义和取值一致。
写一个junit测试类：
package test;

import org.junit.Test;
import org.springframework.test.AbstractDependencyInjectionSpringContextTests;

import test.service.IService;

public class PlainServiceTest extends AbstractDependencyInjectionSpringContextTests{

private IService service;

@Override
protected String[] getConfigLocations() {
return new String[]{"classpath:appctx/**/testApplicationContext.xml"};
}
@Test
public void testAdd() {
TestBean bean=new TestBean();
this.service.add(bean);
}

@Test
public void testDelete() {
TestBean bean=new TestBean();
this.service.delete(bean);
}
public void setService(IService service) {
this.service = service;
}

}
输出：
service add method...
dao add method...
service delete method...
dao delete method...
确实能够工作。如果有bean需要依赖框架自动定义的bean呢？再试试。
写一个简单的bean调用PlainService：
package test.service;

import test.TestBean;

public class DelegateServiceImpl {
private IService plainService;

public void setPlainService(IService plainService) {
this.plainService = plainService;
}

public TestBean add(TestBean bean) {
// TODO Auto-generated method stub
System.out.println("delegate service add method...");
this.plainService.add(bean);
return null;
}


public TestBean delete(TestBean bean) {
// TODO Auto-generated method stub
System.out.println("delegate service delete method...");
this.plainService.delete(bean);
return null;
}

}
配置文件中增加：
<bean id="delegateService" class="test.service.DelegateServiceImpl"></bean>《bean id="delegateService" class="test.service.DelegateServiceImpl"》《/bean》
框架自动配置的bean名称缺省使用以下规则：
类名去掉Impl后缀。比如，PlainServiceImpl在spring容器中配置名称为“plainService”。
再写个junit测试类：
package test;

import static org.junit.Assert.*;

import org.junit.Test;
import org.springframework.test.AbstractDependencyInjectionSpringContextTests;

import test.service.DelegateServiceImpl;

public class DelegateServiceTest extends
AbstractDependencyInjectionSpringContextTests {

private DelegateServiceImpl service;

@Override
protected String[] getConfigLocations() {
return new String[] { "classpath:appctx/**/testApplicationContext.xml" };
}

@Test
public void testAdd() {
TestBean bean = new TestBean();
this.service.add(bean);
}

@Test
public void testDelete() {
TestBean bean = new TestBean();
this.service.delete(bean);
}

public void setService(DelegateServiceImpl service) {
this.service = service;
}

}
输出：
delegate service add method...
service add method...
dao add method...
delegate service delete method...
service delete method...
dao delete method...
感觉非常不错，准备最近有时间一定要好好研究下。</beans></arid:define-beans></arid:define-beans></beans>
