博客展示了Java中邮件发送相关类的代码实现。包含MailAuthenticator类用于邮件认证，StringDataSource类处理字符串数据源，ReMail类实现邮件发送功能，涉及用户名、密码、邮件主题、内容等设置，以及邮件会话和消息的创建与发送。

package yaoyao.classes;

import javax.mail.*;
public class MailAuthenticator extends Authenticator{
private String name=null;//用户名
private String password=null;//用户密码

public MailAuthenticator(){}
public MailAuthenticator(String name, String password){
    this.name=name;
    this.password=password;
}
public void setName(String name){
    this.name=name;
}
public void setPassword(String password){
    this.password=password;
}
public PasswordAuthentication getPasswordAuthentication(){
    return new PasswordAuthentication(name, password);
}
}

------------------------------------------------------------

package yaoyao.classes;

import java.io.*;
import javax.activation.*;

public class StringDataSource implements javax.activation.DataSource{
private String data;
private String type;

public StringDataSource(String data, String type){
this.data=data;
this.type=type;
}

public InputStream getInputStream()throws IOException {
    if(data==null){
      throw new IOException("Data is null");
    }
    return new ByteArrayInputStream(data.getBytes());
    //return new StringBufferInputStream(new String(data.getBytes("iso-8859-1"), "GB2312"));
}
public OutputStream getOutputStream() throws IOException{
    throw new IOException("Data is readonly");
}
public String getContentType(){
    return type;
}
public String getName(){
    return "StringDataSource";
}
}
