Apache Camel 路由中的 Spring Boot 属性使用

2022-01-19 00:00:00 java spring-boot apache-camel

这可以在 Apache Camel 路由中使用 Spring Boot 属性吗?@Value 工作正常，但这是否可以直接放置在表达式的占位符中.

Is this possible to use Spring Boot properties in Apache Camel route? @Value is working fine but is this possible to directly place in place holders of expressions.

更新:我知道 PropertiesComponent，但除了 Applicaiton.yml 之外，这将是我不喜欢的另一种配置.

Update: I know PropertiesComponent but which will be one more configuration apart from Applicaiton.yml that I don't like to have.

application.yml

sftp:
  host:     10.10.128.128
  user:     ftpuser1
  password: ftpuser1password  
  path:     /tmp/inputfile/test1

Spring Boot Apache Camel 路线:

 @Value("${sftp.user}")
    private String sftpUser;

    @Value("${sftp.host}")
    private String sftpHost;

    @Value("${sftp.password}")
    private String sftpPassword;

    @Value("${sftp.path}")
    private String sftpInPath;

    from("sftp://"+sftpUser+"@"+sftpHost+sftpInPath+"?delete=true&password="+sftpPassword)
//this is working

    from("sftp://${sftp.user}@${sftp.host}${sftp.path}?password=${sftp.password}")
// is this possible something like this?

推荐答案

您可以像这样注入完整链接，而不是将所有属性注入到单独的字段中:

Instead of injecting all you properties to separate fields you can inject your full link like that:

@Value("#{'sftp://'+'${sftp.user}'+'@'+'${sftp.host}'+'${sftp.path}'+'?delete=true&password='+'${sftp.password}'}")
private String fullLink;

然后，您可以在 from 方法中使用它.

Then, you can use it in from method.
