代码如下：

import java.util.Properties

import javax.mail.Authenticator

import javax.mail.Message

import javax.mail.Message.RecipientType

import javax.mail.PasswordAuthentication

import javax.mail.Session

import javax.mail.Transport

import javax.mail.internet.InternetAddress

import javax.mail.internet.MimeMessage

public class EmailTest {

public static void main(String[] args) throws Exception{

Properties props = new Properties()

props.setProperty("mail.smtp.auth", "true")

props.setProperty("mail.transport.protocol", "smtp")

props.setProperty("mail.host", "smtp.163.com")

Session session = Session.getInstance(props,

new Authenticator() {

protected PasswordAuthentication getPasswordAuthentication(){

return new PasswordAuthentication("xxx","xxx")//这里分别填写发送email的用户名、密码

}

}

)

session.setDebug(true)

Message msg = new MimeMessage(session)

msg.setFrom(new InternetAddress("xxx"))//这里是发送方的email地址如：[email protected]

msg.setSubject("test javamail")

msg.setRecipients(RecipientType.TO,

InternetAddress.parse("xxx"))//这里是接收方的email地址如：[email protected]

msg.setContent("<a href=\"http://www.google.cn\">谷歌</a>","text/htmlcharset=gb2312")

Transport.send(msg)

}

}

发送邮件时，如果模版不生效，可能是由于模版中的代码有语法错误或者不符合标准，所以导致模版不能正常工作。另外，也可能是由于网络问题，导致邮件发送失败。因此，您需要检查模版中的代码，确保其符合标准，并且检查网络连接是否正常，以确保邮件发送成功。

使用httpClient可以发送，具体的可以参考下面的代码

SSLClient类，继承至HttpClient

import java.security.cert.CertificateException

import java.security.cert.X509Certificate

import javax.net.ssl.SSLContext

import javax.net.ssl.TrustManager

import javax.net.ssl.X509TrustManager

import org.apache.http.conn.ClientConnectionManager

import org.apache.http.conn.scheme.Scheme

import org.apache.http.conn.scheme.SchemeRegistry

import org.apache.http.conn.ssl.SSLSocketFactory

import org.apache.http.impl.client.DefaultHttpClient

//用于进行Https请求的HttpClient

public class SSLClient extends DefaultHttpClient{

public SSLClient() throws Exception{

        super()

        SSLContext ctx = SSLContext.getInstance("TLS")

        X509TrustManager tm = new X509TrustManager() {

                @Override

                public void checkClientTrusted(X509Certificate[] chain,

                        String authType) throws CertificateException {

                }

                @Override

                public void checkServerTrusted(X509Certificate[] chain,

                        String authType) throws CertificateException {

                }

                @Override

                public X509Certificate[] getAcceptedIssuers() {

                    return null

                }

        }

        ctx.init(null, new TrustManager[]{tm}, null)

        SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER)

        ClientConnectionManager ccm = this.getConnectionManager()

        SchemeRegistry sr = ccm.getSchemeRegistry()

        sr.register(new Scheme("https", 443, ssf))

    }

}

HttpClient发送post请求的类

import java.util.ArrayList

import org.apache.http.message.BasicNameValuePair

import org.apache.http.util.EntityUtils

/*

 * 利用HttpClient进行post请求的工具类

public class HttpClientUtil {

public String doPost(String url,Map<String,String> map,String charset){

HttpClient httpClient = null

HttpPost httpPost = null

String result = null

try{

httpClient = new SSLClient()

httpPost = new HttpPost(url)

//设置参数

List<NameValuePair> list = new ArrayList<NameValuePair>()

Iterator iterator = map.entrySet().iterator()

while(iterator.hasNext()){

Entry<String,String> elem = (Entry<String, String>) iterator.next()

}

if(list.size() > 0){

UrlEncodedFormEntity entity = new UrlEncodedFormEntity(list,charset)

httpPost.setEntity(entity)

}

HttpResponse response = httpClient.execute(httpPost)

if(response != null){

HttpEntity resEntity = response.getEntity()

if(resEntity != null){

result = EntityUtils.toString(resEntity,charset)

}

}

}catch(Exception ex){

ex.printStackTrace()

}

return result

}

}

测试代码

import java.util.HashMap

import java.util.Map

//对接口进行测试

public class TestMain {

private String url = "https://192.168.1.101/"

private HttpClientUtil httpClientUtil = null

public TestMain(){

Map<String,String> createMap = new HashMap<String,String>()

createMap.put("authuser","*****")

createMap.put("authpass","*****")

createMap.put("orgkey","****")

createMap.put("orgname","****")

String httpOrgCreateTestRtn = httpClientUtil.doPost(httpOrgCreateTest,createMap,charset)

System.out.println("result:"+httpOrgCreateTestRtn)

}

public static void main(String[] args){

TestMain main = new TestMain()

main.test()

}

}
