.Net使用Hessian调用JAVA的函数

作者：ITPUB论坛编辑： nancy 2008-06-12 00:00

【IT168技术文档】

Hessian其实很像web service，只不过它的协议不是SOAP，而是它自己规定的binary协议。Hessian的server端提供一个servlet基类， client端获得一个service接口（也就是stub）之后调用上面的方法，stub将方法调用marshal之后通过HTTP传到server， server借助reflection调用service方法。
先到http://www.hessiancsharp.org上去下载一个DLL文件（或者直接下载我的Demo，里面有dll和源代码文件），具体源码

第一步：java的设置，简单列举几个类（至于要怎么实现可以看这篇文章）

1 服务

public class HessionServiceImpl implements IHessionService {
private ICmsService cmsService;
public String getHelloWorld() {
return "Hello World";
}
/**//* (non-Javadoc)
* @see com.digitalchina.dcis.domain.service.IHessionService#getStringList()
*/
public List getStringList() {
List list = new ArrayList();
list.add("duck");
list.add("fish");
return list;
}
public List getCmsContentListByLabel(String label,int num){
return this.cmsService.getCmsContentListByLabel(label, num);
}
/**//**
* @param cmsService the cmsService to set
*/
public void setCmsService(ICmsService cmsService) {
this.cmsService = cmsService;
}
}

2 实体类 CmsContent

public class CmsContent  implements Serializable {
public static String PROP_TITLE = "title";
public static String PROP_CONTENT = "content";
public static String PROP_ID = "id";
// constructors
    public CmsContent () {
initialize();
}
protected void initialize () {}
private int hashCode = Integer.MIN_VALUE;
// primary key
    private java.lang.String id;
// fields

private java.lang.String title;
private java.lang.String content;
/**//**
* Return the unique identifier of this class
* @hibernate.id
*  generator-class="uuid.hex"
*  column="ID"
*/
public java.lang.String getId () {
return id;
}
/**//**
* Set the unique identifier of this class
* @param id the new ID
*/
public void setId (java.lang.String id) {
this.id = id;
this.hashCode = Integer.MIN_VALUE;
}
/**//**
* Return the value associated with the column: TITLE
*/
public java.lang.String getTitle () {
return title;
}
/**//**
* Set the value related to the column: TITLE
* @param title the TITLE value
*/
public void setTitle (java.lang.String title) {
this.title = title;
}
/**//**
* Return the value associated with the column: CONTENT
*/
public java.lang.String getContent () {
return content;
}
/**//**
* Set the value related to the column: CONTENT
* @param content the CONTENT value
*/
public void setContent (java.lang.String content) {
this.content = content;
}
public int hashCode () {
if (Integer.MIN_VALUE == this.hashCode) {
if (null == this.getId()) return super.hashCode();
else {
String hashStr = this.getClass().getName() + ":" + this.getId().hashCode();
this.hashCode = hashStr.hashCode();
}
}
return this.hashCode;
}
public String toString () {
return super.toString();
}
}
