SpringBoot项目版本升级:从1.5.3升级到2.1.8版本
前言
简单记录一次本人在自己的SpringBoot项目project-template中,把
1.5.3
版本升级到2.1.8
版本时升级的步骤,及遇到的问题。
提升parent版本号
更改pom文件中parent的版本号
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.8.RELEASE</version>
<relativePath />
</parent>
修改yml文件中的部分配置
在1.5版本中,部分配置与2.1版本有些不同

启动项目遇到的问题
druid-spring-boot-starter版本过低报异常
当版本为1.1.6时,报异常:
... ...
Caused by: java.lang.IllegalStateException: Failed to introspect Class [com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceAutoConfigure] from ClassLoader [[email protected]]
... ...
Caused by: java.lang.NoClassDefFoundError: org/springframework/boot/autoconfigure/jdbc/metadata/DataSourcePoolMetadataProvider
... ...
java.lang.IllegalStateException: Failed to introspect Class [com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceAutoConfigure] from ClassLoader [[email protected]]
... ...
Caused by: java.lang.NoClassDefFoundError: org/springframework/boot/autoconfigure/jdbc/metadata/DataSourcePoolMetadataProvider
... ...
Caused by: java.lang.ClassNotFoundException: org.springframework.boot.autoconfigure.jdbc.metadata.DataSourcePoolMetadataProvider
升级为1.1.10版本即可
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid-spring-boot-starter</artifactId>
<version>1.1.10</version>
</dependency>
SpringSecurity的AuthenticationManager启动报异常
当报异常:
A component required a bean of type 'org.springframework.security.authentication.AuthenticationManager' that could not be found
在SpringSecurity文件中重写即可
@Bean(name = BeanIds.AUTHENTICATION_MANAGER)
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
其他
当报以下异常:
The bean 'userDetailsServiceImpl', defined in class path resource [com/itmacy/dev/auth/security/SecurityConfig.class], could not be registered. A bean with that name has already been defined in file [/Users/chenmeixuan/macy/dev/project/study/webBack/project-template/target/project-template-1.0.0-SNAPSHOT_20200215-1336/classes/com/itmacy/dev/auth/security/UserDetailsServiceImpl.class] and overriding is disabled.
在yml文件中添加以下配置即可
spring:
main:
allow-bean-definition-overriding: true
完结,撒花。。。
