Question

我正在学习在Spring Boot中使用Apache Camel。我正在做一个演示，我正在从FTP位置提取文件并将其拖放到其他位置。

当我直接在from()方法中使用ftps uri时，路由有效。但是，当我尝试将ftps位置存储在application.properties文件中并从那里访问它时，出现了标记无效错误。

这有效：

@Override
    public void configure() throws Exception {
        fromFile();
    }
    public void fromFTP() {
        from("ftps:username@localhost/pickup?password=xxxx&delete=true")
            .to("file:E:/output");
    }

这不是

：

application.properties 文件

ftps.pickup.location=ftps:username@localhost/pickup?password=xxxx

骆驼路线

  @Override
        public void configure() throws Exception {
            fromFile();
        }
        public void fromFTP() {
            from("{{ftps.pickup.location}}&delete=true")
                .to("file:E:/output");
        }

这是我得到的错误：

有人可以指出我要去哪里了吗？预先感谢！

这是Maven过滤的问题。 org.apache.maven.plugins：maven-resources-plugin：2.7：resources中存在一个错误。您得到的错误归结于正在创建的application.properties文件，而不是您的routebuilder中的更改。

springboot pom的父1.5.17.RELEASE引入了maven-resources-plugin 2.7。它具有以下功能，可以对资源文件进行过滤

    <!-- Turn on filtering by default for application properties -->
    <resources>
        <resource>
            <directory>${basedir}/src/main/resources</directory>
            <filtering>true</filtering>
            <includes>
                <include>**/application*.yml</include>
                <include>**/application*.yaml</include>
                <include>**/application*.properties</include>
            </includes>
        </resource>
        <resource>
            <directory>${basedir}/src/main/resources</directory>
            <excludes>
                <exclude>**/application*.yml</exclude>
                <exclude>**/application*.yaml</exclude>
                <exclude>**/application*.properties</exclude>
            </excludes>
        </resource>
    </resources>

使用Springboot parent的版本以及2.7以外的maven-resources-plugin的版本。

例如

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.RELEASE</version>
    <relativePath /> <!-- lookup parent from repository -->
</parent>

从application.properties文件读取值时出现“标记无效”错误
