FreeMarker 配置冲突(Spring 启动)
FreeMarker configuration conflict (Spring Boot)
我有一个 FreeMarker 配置:
@Configuration
public class FreeMarkerConfig {
@Bean
public FreeMarkerConfigurationFactoryBean freeMarkerConfiguration() {
FreeMarkerConfigurationFactoryBean freeMarkerConfigBean = new FreeMarkerConfigurationFactoryBean();
freeMarkerConfigBean.setTemplateLoaderPath("/templates/");
return freeMarkerConfigBean;
}
}
以及来自 build.gradle
的依赖项:
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
implementation 'org.springframework.boot:spring-boot-starter-mail'
implementation 'org.springframework.retry:spring-retry:1.2.5.RELEASE'
compile 'org.freemarker:freemarker:2.3.30'
compileOnly 'org.projectlombok:lombok'
developmentOnly 'org.springframework.boot:spring-boot-devtools'
annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'
annotationProcessor 'org.projectlombok:lombok'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
runtimeOnly 'org.postgresql:postgresql'
}
它工作正常。但是当我在 build.gradle 中设置以下依赖项时:
implementation 'org.springframework.boot:spring-boot-starter-data-rest'
我会得到一个错误:
The bean 'freeMarkerConfiguration', defined in class path resource
[org/springframework/boot/autoconfigure/freemarker/FreeMarkerServletWebConfiguration.class],
could not be registered.
A bean with that name has already been defined in class path resource
[com/lab/myservice/config/FreeMarkerConfig.class]
似乎 spring-data-rest
也提供了配置的 FreeMarker 并且发生了冲突。
@Primary 和@Qualifier 不起作用。
我能做什么?
[更新]
试图将 exclude
添加到我的主 class:
@SpringBootApplication(exclude = {org.springframework.boot.autoconfigure.freemarker.FreeMarkerAutoConfiguration.class})
现在应用程序可以启动,但 FreeMarker 不工作。
找到的解决方案:
在properties中设置(bean名称要相同):spring.main.allow-bean-definition-overriding=true
删除 FreeMarker 自定义配置并使用默认配置。在属性中设置:spring.freemarker.template-loader-path
并使用
implementation 'org.springframework.boot:spring-boot-starter-web'
implementation 'org.springframework.boot:spring-boot-starter-freemarker'
而不是 spring-data-rest
和 org.freemarker:freemarker
