spring-boot - 找不到 org/springframework/boot/bind/RelaxedPropertyResolver

Question

我正在尝试在 Spring Boot 项目中将 Apache Artemis 与 Apache Camel 连接起来。

我在将 spring boot 版本从 1.5.9.RELEASE 升级到 2.2.2.RELEASE 时遇到问题。下面是我正在使用的 POM 和 Java 文件:

当我将父版本升级到 2.2.2.RELEASE 时，它开始出现以下错误:-

我正在使用以下 Java 文件:

package com.learncamel.config;
        
        import org.apache.activemq.camel.component.ActiveMQComponent;
        import org.springframework.context.annotation.Bean;
        import org.springframework.context.annotation.Configuration;
        
        import javax.jms.ConnectionFactory;
        
        @Configuration
        public class ActiveMQConfig {
        
            @Bean(name="activemq")
            public ActiveMQComponent createComponent(ConnectionFactory  factory){
        
                ActiveMQComponent activeMQComponent = new ActiveMQComponent();
                activeMQComponent.setConnectionFactory(factory);
                return activeMQComponent;
        
            }
        }

另一个 Java 文件:

package com.learncamel.routes;
        
        import org.apache.camel.builder.RouteBuilder;
        import org.springframework.stereotype.Component;
        
        @Component
        public class ActiveMQRoute extends RouteBuilder{
        
        
            @Override
            public void configure() throws Exception {
        
        
                from("{{fromRoute}}")
                            .log("Read Message from activemQ ${body}")
                        .to("{{toRoute}}");
        
                }
        }

Answer 1

由于 混合 Spring 版本，可能会出现此类错误。

做一个Maven dependency tree并检查混合的 Spring 版本(父 POM 之一和来自传递依赖项的其他版本。

如果您的依赖树中有混合的 Spring 版本，请使用 dependency management 修复它们或类似的 Maven 功能。
