搭建项目出现报错问题汇总

1.Gateway项目启动出现一下错误Consider defining a bean of type 'org.springframework.http.codec.ServerCodecConfigurer' in your configuration.

***************************
APPLICATION FAILED TO START
***************************

Description:

Parameter 0 of method modifyRequestBodyGatewayFilterFactory in org.springframework.cloud.gateway.config.GatewayAutoConfiguration required a bean of type 'org.springframework.http.codec.ServerCodecConfigurer' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.http.codec.ServerCodecConfigurer' in your configuration.

解决方案：排除web依赖即可。因为gateway和springboot-web不兼容

    <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>

2.pom文件出现灰色且有删除的线解决方案

3.报错Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

***************************
APPLICATION FAILED TO START
***************************

Description:

The bean 'sentinelGatewayFilter', defined in class path resource [com/alibaba/cloud/sentinel/gateway/scg/SentinelSCGAutoConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [com/hjt/config/GatewayConfig.class] and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

问题分析：就是出现bean名字相同不能重复注册

解决方案：

spring
   main:
     allow-bean-definition-overriding: true

4.报错Consider defining a bean of type 'springfox.documentation.schema.TypeNameExtractor' in your configuration.

***************************
APPLICATION FAILED TO START
***************************

Description:

Parameter 0 of constructor in com.github.xiaoymin.knife4j.spring.plugin.DynamicResponseModelReader required a bean of type 'springfox.documentation.schema.TypeNameExtractor' that could not be found.


Action:

Consider defining a bean of type 'springfox.documentation.schema.TypeNameExtractor' in your configuration.

解决方案：在启动类加下注解

@ComponentScan({"springfox.documentation.schema"})

5.引进nacos依赖出现Caused by: java.lang.NoClassDefFoundError: javax/servlet/Filter

引进改依赖即可

        <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-tomcat</artifactId>
      </dependency>

6.knife4j报错 Consider defining a bean of type 'springfox.documentation.schema.TypeNameExtractor' in your configuration.

APPLICATION FAILED TO START

Description:

Parameter 0 of constructor in com.github.xiaoymin.knife4j.spring.plugin.DynamicResponseModelReader required a bean of type 'springfox.documentation.schema.TypeNameExtractor' that could not be found.


Action:

Consider defining a bean of type 'springfox.documentation.schema.TypeNameExtractor' in your configuration.

原因是我配置写了配置了这些东西

knife4j:
  enable: true
  # 开启生产环境屏蔽  true 关闭swagger   false 开启swagger
  production: false

把上面配置删除即可。

7.Caused by: java.lang.ClassNotFoundException: javax.validation.constraints.Size

完整报错如下：

原因分析：没有引入某个类。

解决方案：引入以下依赖即可

   <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-validation</artifactId>
        </dependency>

8.could not find artifact com.hjt:demo-modules:pom:1.0.0.RELAEASE in nexus-aliyun(http://maven.aliyun.com/nexus/content/groups/public)

image

原因分析：看了下是demo-modules这个模块的pom文件找不到

解决方案：把demo-modules中的pom文件注释掉
