FreeMarker配置冲突(Spring )

Question

我有一个FreeMarker配置：

@Configuration
public class FreeMarkerConfig {

    @Bean
    public FreeMarkerConfigurationFactoryBean freeMarkerConfiguration() {
        FreeMarkerConfigurationFactoryBean freeMarkerConfigBean = new FreeMarkerConfigurationFactoryBean();
        freeMarkerConfigBean.setTemplateLoaderPath("/templates/");
        return freeMarkerConfigBean;
    }

}

和来自build.gradle的依赖关系

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'

}

它可以正常工作。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也提供了配置好的FreeMarker，而且冲突也会发生。@主限定符和@限定符无效。我能做什么?

更新

尝试将exclude添加到我的主类：

@SpringBootApplication(exclude = {org.springframework.boot.autoconfigure.freemarker.FreeMarkerAutoConfiguration.class})

现在应用程序可以启动，但是FreeMarker不能工作。

Answer 1

找到解决方案：

属性中设置的spring.main.allow-bean-definition-overriding=true (bean名称应该相同)：

1. 删除FreeMarker自定义配置并使用默认配置。属性设置：spring.freemarker.template-loader-path

和使用

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
