Question

使用spring配置注释加载配置yml。我配置的4个值中的3个值一切正常。但是第4个值为空。

由于其他值正确加载，我认为没有配置错误。我一无所知......

这是我的代码：

YML-文件

spring:
    profiles: test

airtable:
    api-key: xxx
    base: xxx
    proxy: "localhost:8095"
    url: testUrl

mail:
    subjectPrefix: R750Explorer develop -

PropertiesClass

@Configuration
@ConfigurationProperties(prefix = "airtable")
public class AirtableProperties {

@NotNull
private String apiKey;

@NotNull
private String base;

private String proxy;

private String url;


public String getApiKey() {
    return apiKey;
}

public void setApiKey(String apiKey) {
    this.apiKey = apiKey;
}

public String getBase() {
    return base;
}

public void setBase(String base) {
    this.base = base;
}

public String getProxy() {
    return proxy;
}

public void setProxy(String proxy) {
    this.proxy = proxy;
}

public String getUrl() {
    return url;
}

public void setUrl(String url) {
    this.url = url;
}


}

在这里自动发送

public class AirtableRepository {

private final org.slf4j.Logger log = 
LoggerFactory.getLogger(this.getClass());

private Base base = null;

@Autowired
private AirtableProperties prop;

主要申请文件

@SpringBootApplication
@EnableCaching
@EnableScheduling
@EnableConfigurationProperties
public class Application extends SpringBootServletInitializer {


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

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

    SpringApplication.run(Application.class, args);
}
}

所以我得到了我在api-key，base和proxy中定义的值。但是url为null。

更新。我同时使用默认的application.yml和特定于配置文件的application-test.yml

上面的yml是应用程序测试yml。继承人app.yml

spring:
    application:
        name: R750Explorer

    boot:
        admin:
            #url: http://localhost:8085       

    devtools:
        restart:
            additional-paths: src, target
            exclude: "**/*.log"

    mail:
        properties:
            mail:
                smp:
                   connectiontimeout: 5000
                   timeout: 3000
                   writetimeout: 5000

    mvc:
        view:
            prefix: /WEB-INF/jsp/
            suffix: .jsp

    output:
        ansi:
            enabled: ALWAYS

    profiles:
        #default: default
        #active: dev 

    airtable:
        api-key: none-default 

    mail:
        from-address: XXX
        to-address: XXX
        user: XXX
        password: XXX

server:
    address: 127.0.0.1
    #port: 9000
    compression:
        enabled: true
    session:
        cookie:
            #comment: # Comment for the session cookie.
            # domain: # Domain for the session cookie.
            http-only: true
            # -> ein Jahr / Maximum age of the session cookie in seconds.
            max-age: 31536000
            #name:  Session cookie name.
            #path: # Path of the session cookie.
            # "Secure" flag for the session cookie.
            secure: true    

logging:
    file: logs/r750explorer.log
    level:
        com:
            sybit: DEBUG

management:
    context-path: /manage
    security: 
        enabled: false
        # roles: SUPERUSER

security:
    user:
        #name: admin
        #password=****

现在有了线索：如果我在airtable下的默认application.yml中添加url: testurl，它会写入值。但它在application-test.yml中有效。虽然这只是url不是代理等的情况，但它们工作正常。

它对我有用而没有任何改变：

application.yml：

airtable:
    api-key: xxx
    base: xxx
    proxy: localhost:8095
    url: testUrl

POJO：

@Configuration
@ConfigurationProperties(prefix = "airtable")
public class AirtableProperties {

    @NotNull
    private String apiKey;

    @NotNull
    private String base;

    private String proxy;

    private String url;

    public String getApiKey() {
        return apiKey;
    }

    public void setApiKey(String apiKey) {
        this.apiKey = apiKey;
    }

    public String getBase() {
        return base;
    }

    public void setBase(String base) {
        this.base = base;
    }

    public String getProxy() {
        return proxy;
    }

    public void setProxy(String proxy) {
        this.proxy = proxy;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    @Override
    public String toString() {
        return "AirtableProperties{" +
                "apiKey='" + apiKey + '\'' +
                ", base='" + base + '\'' +
                ", proxy='" + proxy + '\'' +
                ", url='" + url + '\'' +
                '}';
    }

输出：

   PROPS ARE AirtableProperties{apiKey='xxx', base='xxx', proxy='localhost:8095', url='testUrl'}

Answer 2

所以我找到了答案。正如我在问题中已经告诉我使用默认的application.yml和application-test.yml。

这两个文件位于单独的资源文件夹中（带有语法的test.yml的副本 - 错误位于src / resource文件夹中）。

删除Copy并实现此结构后，一切正常：

| src / resources /

| - ＆GT; application.yml

| 测试/资源/

| - ＆GT;应用test.yml

由于语法错误和文件的错误放置，它没有成功。感谢所有助手！
