我的项目是springboot+springcloud的，因为安全原因，需要升级版本，所以升级到2.3.10，接下来就是各种报错处理。

一、springboot和springcloud版本对应

二、直接升级到springboot2.3.10.RELEASE

报错如下：

错误原因：

因为springboot的版本和我的springcloud版本不对应导致的错误。

如下是错误版本配置：

<properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><java.version>1.8</java.version><spring-cloud.version>Greenwich.SR6</spring-cloud.version><commons.lang3.version>3.5</commons.lang3.version>
</properties><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement>

Greenwich.SR6 这个版本springcloud不是对应springboot2.3.10这个版本的。所以替换成如下：

 <properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><java.version>1.8</java.version><spring-cloud.version>Hoxton.SR11</spring-cloud.version><commons.lang3.version>3.5</commons.lang3.version></properties>

好了，版本配置完毕，但是这时候在启动的时候，会报以下错误

这个是什么原因导致的呢？是因为sprng-security导致的，如下是配置代码：


@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {@Overrideprotected void configure(HttpSecurity http) throws Exception {super.configure(http);http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.NEVER);// 关闭csrfhttp.csrf().disable();// 支持httpBasichttp.authorizeRequests().anyRequest().authenticated().and().formLogin().loginProcessingUrl("/login").permitAll().and().httpBasic();}@Beanpublic HttpFirewall allowUrlEncodedSlashHttpFirewall() {return new DefaultHttpFirewall();}
}

大家有看到这个super.configure(http);这段代码，就是这段代码导致错误的。版本升级后，只需要将super.configure(http);注释掉就可以了。


@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {@Overrideprotected void configure(HttpSecurity http) throws Exception {//super.configure(http); 注释掉http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.NEVER);// 关闭csrfhttp.csrf().disable();// 支持httpBasichttp.authorizeRequests().anyRequest().authenticated().and().formLogin().loginProcessingUrl("/login").permitAll().and().httpBasic();}@Beanpublic HttpFirewall allowUrlEncodedSlashHttpFirewall() {return new DefaultHttpFirewall();}
}

以上完美解决，版本问题。
