1、创建复杂类:
package lavasoft.suths.pojo;
import java.io.Serializable;
import java.util.Date;
/**
* 一个象征性的复杂类型
*
* @author leizhimin 2009-8-14 17:21:40
*/
public class Foo implements Serializable {
private static final long serialVersionUID = 1792241905841405420L;
private String name;
private Date createtime;
public Foo(String name) {
this.name = name;
createtime = new Date();
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Date getCreatetime() {
return createtime;
}
public void setCreatetime(Date createtime) {
this.createtime = createtime;
}
@Override
public String toString() {
return "Foo{" +
"name='" + name + '\'' +
", createtime=" + createtime +
'}';
}
}
import java.io.Serializable;
import java.util.Date;
/**
* 一个象征性的复杂类型
*
* @author leizhimin 2009-8-14 17:21:40
*/
public class Foo implements Serializable {
private static final long serialVersionUID = 1792241905841405420L;
private String name;
private Date createtime;
public Foo(String name) {
this.name = name;
createtime = new Date();
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Date getCreatetime() {
return createtime;
}
public void setCreatetime(Date createtime) {
this.createtime = createtime;
}
@Override
public String toString() {
return "Foo{" +
"name='" + name + '\'' +
", createtime=" + createtime +
'}';
}
}
2、修改服务接口和实现
public
interface Hello {
String sayHello(String name);
Foo makeFoo(String name);
}
String sayHello(String name);
Foo makeFoo(String name);
}
public
class HelloService
implements Hello {
public String sayHello(String name) {
return "Hello " + name + "!";
}
public Foo makeFoo(String name) {
return new Foo(name);
}
}
public String sayHello(String name) {
return "Hello " + name + "!";
}
public Foo makeFoo(String name) {
return new Foo(name);
}
}
3、部署web,其他的配置都不用改变,并运行tomcat。
4、写客户端测试:
/**
* 客户端调用(会依赖服务接口)
*
* @author leizhimin 2009-8-14 12:29:33
*/
public class Client {
public static void main(String[] args) throws MalformedURLException {
String url = "http://localhost:8080/hessianapp/hessian/hello";
HessianProxyFactory factory = new HessianProxyFactory();
Hello hello = (Hello) factory.create(Hello.class, url);
System.out.println(hello.sayHello("Hessian"));
System.out.println(hello.makeFoo("foo"));
}
}
* 客户端调用(会依赖服务接口)
*
* @author leizhimin 2009-8-14 12:29:33
*/
public class Client {
public static void main(String[] args) throws MalformedURLException {
String url = "http://localhost:8080/hessianapp/hessian/hello";
HessianProxyFactory factory = new HessianProxyFactory();
Hello hello = (Hello) factory.create(Hello.class, url);
System.out.println(hello.sayHello("Hessian"));
System.out.println(hello.makeFoo("foo"));
}
}
运行结果:
Hello Hessian!
Foo{name='foo', createtime=Fri Aug 14 17:32:17 CST 2009}
Process finished with exit code 0
Foo{name='foo', createtime=Fri Aug 14 17:32:17 CST 2009}
Process finished with exit code 0
整合Spring的测试:
/**
* Spring整合Hessian,客户端测试
*
* @author leizhimin 2009-8-14 15:32:46
*/
public class TestClient {
public static void main(String[] args) {
try {
ApplicationContext context = new ClassPathXmlApplicationContext( "/remoting-client.xml");
Hello hello = (Hello) context.getBean( "helloServiceClient");
System.out.println(hello.sayHello( "Spring Hession"));
System.out.println(hello.makeFoo( "SpringFoo"));
}
catch (Exception e) {
e.printStackTrace();
}
}
}
* Spring整合Hessian,客户端测试
*
* @author leizhimin 2009-8-14 15:32:46
*/
public class TestClient {
public static void main(String[] args) {
try {
ApplicationContext context = new ClassPathXmlApplicationContext( "/remoting-client.xml");
Hello hello = (Hello) context.getBean( "helloServiceClient");
System.out.println(hello.sayHello( "Spring Hession"));
System.out.println(hello.makeFoo( "SpringFoo"));
}
catch (Exception e) {
e.printStackTrace();
}
}
}
运行结果:
Hello Spring Hession!
Foo{name='SpringFoo', createtime=Fri Aug 14 17:41:29 CST 2009}
Process finished with exit code 0
Foo{name='SpringFoo', createtime=Fri Aug 14 17:41:29 CST 2009}
Process finished with exit code 0
总结
1、Hessian的序列化做的还不错,可以信赖。
2、序列化对象要实现java.io.Serializable接口。
3、序列化类要有serialVersionUID。
4、注意序列化的规范,有些成员是不能序列化的。
