谷粒商城所遇问题解决：

nacos：

高版本的nacos不再使用Ribbon而是使用spring-cloud-loadbalancer，所以不引入spring-cloud-loadbalancer会报错：

## 解决办法 加入spring-cloud-loadbalancer依赖 并且在nacos中排除ribbon依赖
    <dependencies>
        <dependency>
            <groupId>com.atguigu.gulimall</groupId>
            <artifactId>gulimall-common</artifactId>
            <version>0.0.1-SNAPSHOT</version>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

<!--       加入spring-cloud-loadbalancer依赖-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-loadbalancer</artifactId>
        </dependency>

nacos的config加载

• 先加载nacos上的配置,在加载本地的propertites配置
• 解决P23的config报错 Caused by: com.alibaba.nacos.api.exception.NacosException: endpoint is blank

  在common模块下加入依赖
          <dependency>
              <groupId>org.springframework.cloud</groupId>
              <artifactId>spring-cloud-starter-bootstrap</artifactId>
              <version>3.0.0</version>
          </dependency>

网关模块

解决:@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})失效

@SpringBootApplication(exclude = {
        DataSourceAutoConfiguration.class,
        DataSourceTransactionManagerAutoConfiguration.class,
        DruidDataSourceAutoConfigure.class ,
        HibernateJpaAutoConfiguration.class})

解决:Spring MVC found on classpath, which is incompatible with Spring Cloud Gateway

排除spring-boot-starter-web依赖  网关模块
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-web</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

        <dependency>
            <groupId>com.atguigu.gulimall</groupId>
            <artifactId>gulimall-common</artifactId>
            <version>0.0.1-SNAPSHOT</version>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-web</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
