Spring Boot 版本升级2.2.11.RELEASE至2.7.4

2.2.11.RELEASE ===> 2.7.4

项目更新spring-boot-starter-parent 主依赖，导致项目跑不起了

日志也没有输出有用信息，自己查看源码调试

启动入口打断点，一步步进入方法定位项目停止代码

我的项目执行到SpringApplication.class 的152行代码会停止项目

1、org.springframework.boot.context.config.InactiveConfigDataAccessException: Inactive property source 'Config resource 'class path resource [application.properties]' via location 'optional:classpath:/'' imported from location 'class path resource [application.properties]' cannot contain property 'spring.profiles.active' [origin: class path resource [application.properties] - 1:24]

application.properties

弃用：spring.profiles.active=dev 转换：spring.config.activate.on-profile=dev（如果没有报错可以不管）

2、java.lang.ClassNotFoundException: com.fasterxml.jackson.databind.ser.std.ToStringSerializerBase

升级：jackson 版本 2.10以上

ToStringSerializerBase是jackson2.10新增的类

3、org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'winMigrationImpl': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'spring.datasource.driver-class-name' in value "${spring.datasource.driver-class-name}"

报错：SpringApplication.class 158行 this.refreshContext(context);

Error creating bean with name 'winMigrationImpl': Injection of autowired dependencies failed

原因：没有读取到配置文件

4、项目循环引用

按提示添加 配置 spring.main.allow-circular-references=true

5、PatternsRequestCondition.getPatterns()报错："this.condition" is null

Spring Boot整合Swagger问题

解决：

1、添加配置项

spring.mvc.pathmatch.matching-strategy=ant_path_matcher

2、webconfig添加 （单独第一步不行，就两个都加上）

import org.springframework.boot.actuate.autoconfigure.endpoint.web.CorsEndpointProperties;
import org.springframework.boot.actuate.autoconfigure.endpoint.web.WebEndpointProperties;
import org.springframework.boot.actuate.autoconfigure.web.server.ManagementPortType;
import org.springframework.boot.actuate.endpoint.ExposableEndpoint;
import org.springframework.boot.actuate.endpoint.web.*;
import org.springframework.boot.actuate.endpoint.web.annotation.ControllerEndpointsSupplier;
import org.springframework.boot.actuate.endpoint.web.annotation.ServletEndpointsSupplier;
import org.springframework.boot.actuate.endpoint.web.servlet.WebMvcEndpointHandlerMapping;
import org.springframework.context.annotation.Bean;
import org.springframework.core.env.Environment;
import org.springframework.util.StringUtils;import java.util.ArrayList;
import java.util.Collection;
import java.util.List;@Bean
public WebMvcEndpointHandlerMapping webEndpointServletHandlerMapping(WebEndpointsSupplier webEndpointsSupplier, ServletEndpointsSupplier servletEndpointsSupplier, ControllerEndpointsSupplier controllerEndpointsSupplier, EndpointMediaTypes endpointMediaTypes, CorsEndpointProperties corsProperties, WebEndpointProperties webEndpointProperties, Environment environment) {List<ExposableEndpoint<?>> allEndpoints = new ArrayList();Collection<ExposableWebEndpoint> webEndpoints = webEndpointsSupplier.getEndpoints();allEndpoints.addAll(webEndpoints);allEndpoints.addAll(servletEndpointsSupplier.getEndpoints());allEndpoints.addAll(controllerEndpointsSupplier.getEndpoints());String basePath = webEndpointProperties.getBasePath();EndpointMapping endpointMapping = new EndpointMapping(basePath);boolean shouldRegisterLinksMapping = this.shouldRegisterLinksMapping(webEndpointProperties, environment, basePath);return new WebMvcEndpointHandlerMapping(endpointMapping, webEndpoints, endpointMediaTypes, corsProperties.toCorsConfiguration(), new EndpointLinksResolver(allEndpoints, basePath), shouldRegisterLinksMapping, null);
}private boolean shouldRegisterLinksMapping(WebEndpointProperties webEndpointProperties, Environment environment, String basePath) {return webEndpointProperties.getDiscovery().isEnabled() && (StringUtils.hasText(basePath) || ManagementPortType.get(environment).equals(ManagementPortType.DIFFERENT));
}

6、java.lang.NoSuchMethodError: org.springframework.boot.actuate.autoconfigure.web.server.ManagementServerProperties.getServlet()Lorg/springframework/boot/actuate/autoconfigure/web/server/ManagementServerProperties$Servlet;

依赖升级到2.4.1，原2.3.1版本没有这个方法

<!-- 监控健康-->
<dependency><groupId>de.codecentric</groupId><artifactId>spring-boot-admin-starter-client</artifactId><version>2.4.1</version>
</dependency>

6、IllegalArgumentException: When allowCredentials is true, allowedOrigins cannot contain the special value "*" since that cannot be set on the "Access-Control-Allow-Origin" response header. To allow credentials to a set of origins, list them explicitly or consider using "allowedOriginPatterns" instead.

IllegalArgumentException: When allowCredentials is true, allowedOrigins cannot contain the special value "*" since that cannot be set on the "Access-Control-Allow-Origin" response header. To allow credentials to a set of origins, list them explicitly or consider using "allowedOriginPatterns" instead.

解决：

项目配置 MipsConf.class

@Bean
public WebMvcConfigurer corsConfigurer() {    return new WebMvcConfigurer() {        @Override        public void addCorsMappings(CorsRegistry registry) {            registry.addMapping("/**")                    //.allowedOrigins("*")                    .allowedOriginPatterns("*")                    .allowCredentials(true).allowedMethods("GET", "POST", "DELETE", "PUT","PATCH").maxAge(3600);}};
}

allowedOrigins("*") 替换成 allowedOriginPatterns("*")

7、fastjson 升级 1.2.83

以前版本有漏洞，1.2.83 修复
