在 Spring Boot 应用程序中,我想使用@ConfigurationProperties
具有相同前缀的注释来根据配置文件配置我的两个数据源。为什么 Spring Boot 配置处理器禁止它?gradle报错是:
...
:compileJava ... error: Duplicate `@ConfigurationProperties` definition for prefix 'spring.datasource'
笔记:
- “运行方式-> Spring Boot App”在 STS 中有效
- 没有 spring-boot-configuration-processor 依赖,gradle build 工作(但
When using @ConfigurationProperties it is recommended to add 'spring-boot-configuration-processor' to your classpath to generate configuration metadata
出现警告)
构建.gradle
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.5.6.RELEASE")
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
repositories {
mavenCentral()
maven { url "https://repository.jboss.org/nexus/content/repositories/releases" }
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
dependencies {
compile("org.springframework.boot:spring-boot-starter-data-jpa")
compile 'org.springframework.boot:spring-boot-configuration-processor:1.5.4.RELEASE'
compile("com.h2database:h2")
}
应用程序属性
spring.datasource.driverClassName = org.h2.Driver
spring.datasource.username = sa
spring.datasource.password = sa
你好。申请
@SpringBootApplication
public class Application {
public static void main(final String[] args) {
final SpringApplication app = new SpringApplication(Application.class);
app.setAdditionalProfiles("prod");
app.run();
}
@Bean
@Profile("dev")
@ConfigurationProperties("spring.datasource")
public DataSource dataSourceDev() {
return DataSourceBuilder
.create()
.url(generateDevUrl())
.build();
}
@Bean
@Profile("prod")
@ConfigurationProperties("spring.datasource")
public DataSource dataSourceProd() {
return DataSourceBuilder
.create()
.url(generateProdUrl())
.build();
}
}
提前致谢
