java - 继续接收javax.mail.Session$1 : method <init>()V not found when trying to send an email using Springboot + mvc

Question

这是生成错误的代码:

import com.cisco.s3.util.Logging;
import javax.mail.internet.MimeMessage;
import org.slf4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.io.ClassPathResource;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class EmailController {

    private static final Logger log = Logging.getLogger(EmailController.class);

    @Autowired
    private JavaMailSender sender;

    @RequestMapping("/simpleemail")
    @ResponseBody
    String home() {
        try {
            sendEmail();
            return "Email Sent!";
        }catch(Exception ex) {
            return "Error in sending email: " + ex;
        }
    }

    private void sendEmail() throws Exception{
        MimeMessage message = sender.createMimeMessage();

        // Enable the multipart flag!
        MimeMessageHelper helper = new MimeMessageHelper(message,true);

        helper.setTo("arterome@cisco.com");
        helper.setFrom("security-orchestration@cisco.com");
        helper.setText("How are you?");
        helper.setSubject("Hi");

        ClassPathResource file = new ClassPathResource("cat.jpg");
        helper.addAttachment("eagle.jpg", file);

        sender.send(message);
    }
}

错误很长，我添加一段:

```
[ERROR] 2019-05-22 09:14:17 @ org.apache.catalina.core.ContainerBase.[Tomcat].[localhost].[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Handler dispatch failed; nested exception is java.lang.NoSuchMethodError: javax.mail.Session$1: method <init>()V not found] with root cause

    ```

我已经阅读了很多有关同一个项目的文章，它似乎是某个地方的兼容性问题，但我只是无法跟踪它。

我使用 gradle 作为依赖项:

dependencies {
    compile 'com.cisco.s3:soar-toolbox:2.0.0-beta.31'
    compile 'org.apache.tomcat.embed:tomcat-embed-jasper'
    compile 'org.slf4j:jcl-over-slf4j'
    compile 'org.slf4j:jul-to-slf4j'
    compile 'org.springframework.boot:spring-boot-starter-actuator'
    compile 'org.springframework.boot:spring-boot-starter-security'
    compile 'org.springframework.boot:spring-boot-starter-web'
    compile'org.springframework.boot:spring-boot-starter-mail'
    compile 'org.springframework.security:spring-security-ldap'
    compile group: 'org.mongodb', name: 'mongo-java-driver', version: '3.10.2'
    testCompile 'org.springframework.boot:spring-boot-starter-test'
    testCompile 'org.springframework.security:spring-security-test'
}

自一周前以来，我一直在尝试解决此问题，但成功率为零。

谢谢!!!

NoSuchMethodError 表示 com.cisco.s3:soar-toolbox:2.0.0-beta.31 依赖项与 javax.mail 不兼容code> 您正在运行的版本。

soar-toolbox 看起来是专有的，因此您必须引用 Cisco 提供的文档来了解支持哪些 Java 和 Java EE 版本。
