    //sqlSessionFactory 当看到这个报错就知道是数据源没有找到,但是我这个服务本来是能正常启动的所以我就排除我数据源的问题,因为引入了 javaMelody与springboot的整合所以我认为应该是mybatisplus与javaMelody出现冲突,
    Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [com/baomidou/mybatisplus/autoconfigure/MybatisPlusAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.ibatis.session.SqlSessionFactory]: Factory method 'sqlSessionFactory' threw exception; nested exception is com.baomidou.mybatisplus.core.exceptions.MybatisPlusException: Error: GlobalConfigUtils setMetaData Fail !

    开始我引入的是spring boot 与javaMelody的starter

     //原引入的版本
     <dependency>
                <groupId>net.bull.javamelody</groupId>
                <artifactId>javamelody-spring-boot-starter</artifactId>
                <version>1.76.0</version>
    </dependency>
    
    //不引入了starter了直接引入jar了
     <dependency>
                <groupId>net.bull.javamelody</groupId>
                <artifactId>javamelody-core</artifactId>
                <version>1.79.0</version>
    </dependency>
    
    在配置类中把javaMelody注册到spirng中
        @Bean
        //配置注册顺序
        @Order(Integer.MAX_VALUE - 1)
        public FilterRegistrationBean monitoringFilter() {
            FilterRegistrationBean registration = new FilterRegistrationBean();
            registration.setFilter(new MonitoringFilter());
            registration.addUrlPatterns("/*");
            registration.setName("monitoring");
            return registration;
        }
    //
        /**
         * 配置javamelody监听器sessionListener
         */
        @Bean
        public ServletListenerRegistrationBean<SessionListener> servletListenerRegistrationBean() {
            ServletListenerRegistrationBean<SessionListener> slrBean = new ServletListenerRegistrationBean<SessionListener>();
            slrBean.setListener(new SessionListener());
            return slrBean;
        }
    
    
    
    然后项目正常启动问题解决
