小编yaz*_*ara的帖子

我有一个简单的主应用程序:

@Configuration
    @EnableAutoConfiguration
    @ComponentScan(basePackages = "dreamteam.eho")
    @Import({EhoConfig.class})
    public class MainApp implements CommandLineRunner, ApplicationContextAware {

配置:

@Configuration
@EnableConfigurationProperties({RootProperties.class})
public class EhoConfig {
}

和属性:

@ConfigurationProperties("root")
public class RootProperties {
    private String name;

我尝试加载配置:

--spring.config.location=file:///E:/.../eho-bot/props/ --spring.profiles.active=eho

路径是正确的.但是没有加载yml;

application-eho.yml文件:

logging:
  file: D:/java/projects/telegram-bots/eho.log
  level:
    dreamteam.eho: INFO
    org.springframework: DEBUG

root:
  name: EHO-BOT

应用程序使用args运行,但所有props都为null.记录属性不适用; SOUT:

--spring.config.location=file:///E:.../eho-bot/props/

--spring.profiles.active=eho

--spring.output.ansi.enabled=always

我有maven项目.Maven构建完整的SUCCESS.但我不能做这个项目.

[信息]建立成功

项目包含一个模块.Idea无法看到依赖关系.

需要通过带有弹簧轮廓的gradle进行测试.

gradle clean build

我添加了任务:

task beforeTest() {
    doLast {
      System.setProperty("spring.profiles.active", "DEV")
    }
}

test.dependsOn beforeTest

我的测试定义是:

@RunWith(SpringRunner.class)
@SpringBootTest
@ActiveProfiles("TestProfile")
public class SomeTest {

但这种结构对我不起作用.

Gradle运行测试.

有一个 Eureka Server 应用程序：

@EnableEurekaServer
@SpringBootApplication
public class RegistrationModulesServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(RegistrationModulesServiceApplication.class, args);
    }
}

使用 appplicaton.yml 配置（默认）：

eureka:
  instance:
    hostname: localhost
  client: 
    registerWithEureka: false
    fetchRegistry: false

server:
  port: 1111  

在第一次运行时 - 我看到了带有状态的仪表板。就像在文档中一样：

然后 - 重启后我只能看到 xml 响应：

为什么？

日志中没有错误。

有一个带有配置的 Spring Boot 应用程序：

spring:
  jpa:
    show-sql: true
    properties:
      hibernate:
        jdbc:
          batch_size: 20
        order_inserts: true
        order_updates: true
        generate_statistics: true
        format_sql: true
        dialect: org.hibernate.dialect.PostgreSQL10Dialect
        default_schema: ${SCHEMA}

我使用 JpaRepository.saveAll 方法将新数据插入数据库。但我认为批处理不起作用。

有日志：
