Spring Boot忽略其他属性文件

Question

我在应用程序中设置了以下Maven多模块。属性以及模块A中相应的属性类和配置：

@Component
@ConfigurationProperties(prefix = "city")
@Getter
@Setter
@ToString
public class CityProperties {
    private int populationAmountWorkshop;
    private double productionInefficientFactor;
    private Loaner loaner = new Loaner();
    private Tax tax = new Tax();
    private Guard pikeman = new Guard();
    private Guard bowman = new Guard();
    private Guard crossbowman = new Guard();
    private Guard musketeer = new Guard();

    @Getter
    @Setter
    @ToString
    public static class Loaner {
        private int maxRequest;
        private int maxAgeRequest;
        private int maxNbLoans;
    }

    @Getter
    @Setter
    @ToString
    public static class Tax {
        private double poor;
        private double middle;
        private double rich;
        private int baseHeadTax;
        private int basePropertyTax;
    }

    @Getter
    @Setter
    @ToString
    public static class Guard {
        private int weeklySalary;
    }
}

应用程序。特性：

#City
# Amount of inhabitants to warrant the city to have one workshop
city.populationAmountWorkshop=2500
# Factor that is applied on the efficient production to get the inefficient production
city.productionInefficientFactor=0.6
# Maximum requests per loaner
city.loaner.maxRequest=6
# Maximum  age of loan request in weeks
city.loaner.maxAgeRequest=4
# Maximum loan offers per loaner
city.loaner.maxNbLoans=3
# Weekly tax value factor for the various population per 100 citizens
city.tax.poor=0
city.tax.middle=0.6
city.tax.rich=2.0
city.tax.baseHeadTax=4
city.tax.basePropertyTax=280
city.pikeman.weeklySalary=3
city.bowman.weeklySalary=3
city.crossbowman.weeklySalary=4
city.musketeer.weeklySalary=6

以及配置

@Configuration
@ComponentScan(basePackageClasses = AConfiguration.class)
public class AConfiguration {
}

然后是模块C和我的应用程序：

@SpringBootApplication
@Import({CConfiguration.class})
public class SpringBootApp {

    public static void main(String[] args) {
        SpringApplicationBuilder builder = new SpringApplicationBuilder(SpringBootApp.class);
        ApplicationContext context = builder.profiles("server").run();
        CityProperties cityProperties = context.getBean(CityProperties.class);
        System.out.println(cityProperties);
    }
}

相关配置：

@Configuration
@Import(AConfiguration.class)
@ComponentScan(basePackageClasses = {CConfiguration.class, DComponents.class})
@PropertySource("classpath:bean-test.properties")
public class CConfiguration {
    @Autowired
    @Qualifier("serverThreadPool")
    private Executor serverThreadPool;
    @Autowired
    private SubscriberExceptionHandler subscriptionExceptionHandler;

    @Bean
    public AsyncEventBus serverEventBus() {
        return new AsyncEventBus(serverThreadPool, subscriptionExceptionHandler);
    }

    @Bean
    @Primary
    @ConfigurationProperties(prefix = "city")
    public CityProperties cityProperties() {
        return new CityProperties();
    }
}

还有豆子测试。属性文件：

spring.main.allow-bean-definition-overriding=true

从CConfiguration中删除最后一个bean时，应用程序将启动。但是，有了这个bean定义，我得到了以下错误：

描述：无法注册在类路径资源[c/CConfiguration.class]中定义的bean“cityProperties”。已在文件[/module1/target/classes/A/CityProperties.class]中定义了具有该名称的bean，并且已禁用重写。

操作：考虑重命名一个bean或通过设置spring.main.allow-bean-定义-重写=true启用重写

这正是我在bean测试中定义的。财产。然而，这似乎被忽视了。起初我认为属性文件甚至没有加载，但当在PropertySource中拼写错误时，我得到了一个错误，即在类路径上找不到该文件，这表明该文件是由Spring提取的，但其内容被忽略了。

Answer 1

我认为

@PropertySource("classpath:bean-test.properties")

将仅用于自定义特性，而不用于Spring特性。试着把

spring.main.allow-bean-definition-overriding=true

在应用程序中。财产。
