添加Redis依赖项时，创建名称为'requestMappingHandlerAdapter'的bean时出错

在我的spring boot应用程序中，我面临以下问题。

在build.gradle文件中添加了以下依赖项

compile('org.springframework.boot:spring-boot-starter-data-redis-reactive')

已添加到Application.java文件中

@Bean
public ReactiveRedisConnectionFactory reactiveRedisConnectionFactory() {
    return new LettuceConnectionFactory("localhost", 6379);
}

@Bean
public ReactiveRedisTemplate<String, String> reactiveRedisTemplateString() {
    return new ReactiveRedisTemplate<>(reactiveRedisConnectionFactory(),
            RedisSerializationContext.string());
}

在服务类ApplicationService.java

中 
@Autowired
ReactiveRedisTemplate<String, String> reactiveRedisTemplateString;

，我正在使用此模板向Redis添加键和值。 启动服务器时，我遇到了下面的异常。但是，如果我在Application.java类的下面添加行，则不会出现该异常，但是Controller类的请求映射将不起作用。

@EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class,WebMvcAutoConfiguration.class })

遇到错误

此错误仅出现在我的项目中，我将创建一个简单的项目以供Redis插入，然后它将起作用。请帮我解决问题。
