看看两段简单的JAVA代码,我们用它作为WSDL的服务实现代码:
//CatDTO.java
public class CatDTO
{
private long id;
private String name;
public long getId()
{
return id;
}
public String getName()
{
return name;
}
public void setId(long id)
{
this.id = id;
}
public void setName(String name)
{
this.name = name;
}
}
//Test.java
public class Test
{
public String echo(CatDTO cd){
return "Hello " + cd.getName();
}
}
然后看看用它导出的WSDL:
