第一種方法

試過(guò)在module1-service中添加自定義datasource(只支持properties，Yml可能能實(shí)現(xiàn)，但還不太會(huì)寫)，可以實(shí)現(xiàn)(此種方式不清楚是否會(huì)影響原來(lái)spring datasource機(jī)制，對(duì)spring原理不熟)
代碼如下：

@Component
@ConfigurationProperties(prefix = "spring.datasource")
@PropertySource("classpath:service-jdbc.properties")
public class MyDataSourceProperties {
    private String url;
    ...
}

@EnableConfigurationProperties(MyDataSourceProperties.class)
public class MyDataSourceConfig {
    @Autowired
    private MyDataSourceProperties myDataSourceProperties;
    @Bean
    @Primary
    public DataSource dataSource() {
        return DataSourceBuilder.create(myDataSourceProperties.getClassLoader()).type(myDataSourceProperties.getType()).driverClassName(myDataSourceProperties.determineDriverClassName()).url(myDataSourceProperties.determineUrl()).username(myDataSourceProperties.determineUsername()).password(myDataSourceProperties.determinePassword()).build();
    }
}

第二種方法

在module1-service中自定義properties bean(此種方法較好，推薦),代碼如下

@Configuration
public class ServiceConfig {
    @Bean
    public static PropertySourcesPlaceholderConfigurer properties() {
        PropertySourcesPlaceholderConfigurer configurer = new PropertySourcesPlaceholderConfigurer();
        YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
        yaml.setResources(new ClassPathResource("application-module1-service.yml"));
        configurer.setProperties(yaml.getObject());
        return configurer;
    }
}

由第二種用法引起的新的問(wèn)題：

項(xiàng)目中如果存在多環(huán)境配置文件，如application-module1-service-dev.yml/application-module1-service-test.yml/application-module1-service/-release.yml時(shí)，怎樣根據(jù)module1-web中配置的spring.profiles.active加載對(duì)應(yīng)的配置文件？
思路為在加載文件時(shí)使用SpringContextUtil獲取配置文件中的active，在properties()中根據(jù)active加載文件
代碼如下：

SpringContextUtil.java

@Order(Integer.MIN_VALUE)
@Component
public class SpringContextUtil implements ApplicationContextAware {

    private static ApplicationContext context = null;
    @Override
    public void setApplicationContext(ApplicationContext applicationContext)
            throws BeansException {
        this.context = applicationContext;
    }
    /// 獲取當(dāng)前環(huán)境
    public static String getActiveProfile() {
        return context.getEnvironment().getActiveProfiles()[0];
    }
    /// 獲取當(dāng)前環(huán)境
    public static String[] getActiveProfiles() {
        return context.getEnvironment().getActiveProfiles();
    }
}

ServiceConfig

    @Bean
    public static PropertySourcesPlaceholderConfigurer properties() {
        PropertySourcesPlaceholderConfigurer configurer = new PropertySourcesPlaceholderConfigurer();
        String path = "application-module1-service.yml";
        try {
            String profile = SpringContextUtil.getActiveProfile();
            if (StringUtils.isNotBlank(profile)) {
                path = "application-module1-service-" + profile + ".yml";
            }
        }catch (NullPointerException e){
            e.printStackTrace();
            System.out.println("SpringContextUtil...未加載...");
        }
        YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
        yaml.setResources(new ClassPathResource(path));//File引入
        configurer.setProperties(yaml.getObject());
        return configurer;
    }

然而這里會(huì)有循環(huán)依賴問(wèn)題
運(yùn)行代碼會(huì)有

SpringContextUtil...未加載...

沒有實(shí)現(xiàn)根據(jù)active加載對(duì)應(yīng)配置文件

用application.yml配置無(wú)非也是生產(chǎn)bean, 比如你示例代碼中application-module1-service.yml:

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://140.143.26.196:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false&autoReconnect=true
    username: test
  

可以在編碼中這樣去實(shí)現(xiàn):

@Bean
@Primary
public DataSource dataSource() {
    return DataSourceBuilder
        .create()
        .username("")
        .password("")
        .url("")
        .driverClassName("")
        .build();
}
