"Mark Invalid" 从 application.properties 文件读取值时出错

Question

我正在学习使用带 Spring 引导的 Apache Camel。我正在做一个演示，我从 FTP 位置拾取文件并将其放到另一个位置。

当我在 from() 方法中直接使用 ftps uri 时，该路由有效。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，我收到 Mark Invalid 错误。

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");
        }

这是我收到的错误：

谁能指出我哪里出错了？提前致谢！

这是 Maven 过滤的问题。 org.apache.maven.plugins:maven-resources-plugin:2.7:resources 中存在错误。您收到的错误归因于正在创建的 application.properties 文件，而不是您的路由构建器中的更改。

springboot pom的parent 1.5.17.RELEASE引入了maven-resources-plugin 2.7。它具有以下内容以对资源文件应用过滤

    <!-- 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 maven-resources-plugin 版本不是 2.7 的 springboot 父版本。

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>
