spring boot 2.0 升级指南

Spring Boot Security 2.0升级指南

pom文件修改

• choerodon-framework-parent升级为0.9.0.RELEASE
• choerodon.starters.version升级为0.10.0.RELEASE
• spring-cloud-starter-eureka => spring-cloud-starter-netflix-eureka-client
• spring-cloud-starter-zuul => spring-cloud-starter-netflix-zuul
• spring-cloud-starter-feign => spring-cloud-starter-openfeign
• spring-cloud-starter-eureka-server => spring-cloud-starter-netflix-eureka-server

单元测试

单元测试报如下：

java.lang.IllegalStateException: Failed to transform class with name io.choerodon.iam.app.service.impl.AccessTokenServiceImplSpec. Reason: null
...
Caused by: java.util.ConcurrentModificationException
...

或者

java.lang.IllegalStateException: Failed to load ApplicationContext
...
Caused by: java.lang.IllegalStateException: Could not initialize plugin: interface org.mockito.plugins.MockMaker
...
Caused by: java.lang.NoClassDefFoundError: org/mockito/cglib/proxy/MethodInterceptor
...
Caused by: java.lang.ClassNotFoundException: org.mockito.cglib.proxy.MethodInterceptor

解决方法：

• powermock.version 1.7.4 => 2.0.0-beta.5
• powermock-api-mockito => powermock-api-mockito2
• 添加指定版本javassist

        <dependency>
            <groupId>org.javassist</groupId>
            <artifactId>javassist</artifactId>
            <version>3.24.0-GA</version>
        </dependency>

如果单元测试里有自己mock的DiscoveryClient，需要在application-test.yml文件中将Spring boot 2.0自动注入的几个DiscoveryClient排除掉，否则会报primary bean冲突的问题

spring:
  autoconfigure:
    exclude:
      - org.springframework.boot.autoconfigure.liquibase.LiquibaseAutoConfiguration
      - org.springframework.boot.autoconfigure.kafka.KafkaAutoConfiguration
      - org.springframework.cloud.client.discovery.simple.SimpleDiscoveryClientAutoConfiguration
      - org.springframework.cloud.client.discovery.composite.CompositeDiscoveryClientAutoConfiguration
      - org.springframework.cloud.client.discovery.noop.NoopDiscoveryClientAutoConfiguration

配置修改

• spring.http.multipart => spring.servlet.multipart
• management.port => management.server.port
• 许多server.*属性 ( Servlet 特有的) 已经转移到server.servlet.*， 比如server.context-path --> server.servlet.context-path
• security.ignored被移除，使用代码替代@Value("${security.ignored:/choerodon/**")
• management.security.*去除，默认只有端点/health和/info是暴露的,开放所有端点可以使用management.endpoints.web.exposure.include=*
• endpoints.<id>.enabled修改为management.endpoint.<id>.enabled

chart修改

• 修改deployment.yaml的readinessProbe探针，localhost:{{ .Values.deployment.managementPort }}/health => localhost:{{ .Values.deployment.managementPort }}/actuator/health
• 修改values.yaml中的metrics.path /prometheus=>/actuator/prometheus

导入包

• org.springframework.cloud.netflix.feign => org.springframework.cloud.openfeign
• org.springframework.boot.bind不再可用，并被新的宽松绑定规则所取代, RelaxedDataBinder被Binder取代
