spring cloud 版本升级 Daloston---> Finchley

加入下边依赖,帮助检测迁移过程中存在的问题
在Finchley 中,spring boot 升级到2.x ,其中配置文件中的参数需要全部小写,或者用 - 隔开.

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-properties-migrator</artifactId>
            <scope>runtime</scope>
        </dependency>

1.父级包的导入变更

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.6.RELEASE</version>
        <relativePath/>
    </parent>
      <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Finchley.SR2</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

2.eureka server

1.1 增强安全机制,

@EnableWebSecurity
class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().ignoringAntMatchers("/eureka/**");
        super.configure(http);
    }
}

1.2 依赖变更

Dalostion版本

  <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
  </dependency>

Finchley版本

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>

3.eureka client

依赖升级

Daloston

       <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
        </dependency>

FinchleySR2

      <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>

4.zuul

1.依赖升级
Daloston

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zuul</artifactId>
        </dependency>

FinchleySR2

      <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
        </dependency>
  1. 关于 ZuulFallbackProvider ----> FallbackProvider

finchleySR2版本中, 对zuulFallbackeProvider进行了调整,

FinchleySR2版本: 能够获得更多的熔断的错误信息和路由信息
@Override
    public ClientHttpResponse fallbackResponse(String route, Throwable cause) {
        return new ClientHttpResponse() {
            @Override
            public HttpStatus getStatusCode() throws IOException {
                return HttpStatus.OK;
            }

            @Override
            public int getRawStatusCode() throws IOException {
                return HttpStatus.OK.value();
            }

            @Override
            public String getStatusText() throws IOException {
                return HttpStatus.OK.getReasonPhrase();
            }

            @Override
            public void close() {
            }

            @Override
            public InputStream getBody() throws IOException {
                JSONObject body = new JSONObject();
                body.put("code", ApiConstant.RESPONSE_SYSTEM_BUSY_ERROR_CODE);
                body.put("msg", ApiConstant.RESPONSE_SYSTEM_BUSY_ERROR_MSG);
                body.put("data", "");
                return new ByteArrayInputStream(body.toJSONString().getBytes("UTF-8"));
            }

            @Override
            public HttpHeaders getHeaders() {
                HttpHeaders headers = new HttpHeaders();
                //和body中的内容编码一致，否则容易乱码
                headers.setContentType(MediaType.APPLICATION_JSON_UTF8);
                return headers;
            }
        };
    }

Daloston版本:

    @Override
    public ClientHttpResponse fallbackResponse() {

        return new ClientHttpResponse() {
            @Override
            public HttpStatus getStatusCode() throws IOException {
                return HttpStatus.OK;

            }

            @Override
            public int getRawStatusCode() throws IOException {
                return HttpStatus.OK.value();
            }

            @Override
            public String getStatusText() throws IOException {
                return HttpStatus.OK.getReasonPhrase();
            }

            @Override
            public void close() {
            }

            @Override
            public InputStream getBody() throws IOException {
                JSONObject body = new JSONObject();
                body.put("code", ApiConstant.RESPONSE_SYSTEM_BUSY_ERROR_CODE);
                body.put("msg", ApiConstant.RESPONSE_SYSTEM_BUSY_ERROR_MSG);
                body.put("data", "");
                return new ByteArrayInputStream(body.toJSONString().getBytes("UTF-8"));
            }

            @Override
            public HttpHeaders getHeaders() {
                HttpHeaders headers = new HttpHeaders();
                //和body中的内容编码一致，否则容易乱码
                headers.setContentType(MediaType.APPLICATION_JSON_UTF8)
                return headers;
            }
        };
    }

3 zuul 关于ribbon的比较重要的配置, 主要在于文件上传

ribbon.ReadTimeout=60000
ribbon.ConnectTimeout=3000

5.Hystrix

7.Feign

1.依赖
Daloston

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-feign</artifactId>
        </dependency>

       <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign</artifactId>
        </dependency>
  1. 配置
feign.httpclient.enabled=true
feign.okhttp.enabled=true

8.Spring boot admin

1.配置变化

 ## 该语句的过时的替代方式
 management.security.enabled=false
 #在spring boot 2.x 中的替代方案为
 management.endpoints.web.exposure.exclude=*
  1. tomcat 中类的变更 ,在需要同事兼容http和https协议,同时开发多个端口的时候需要注意
    EmbeddedServletContainerFactory----> TomcatServletWebServerFactory
  2. spirng boot 2.x 不在兼容支持日志 org.apache.log4j.Logger

mybatis 的支持

无变化

spring boot redis的支持

  1. 默认的链接客户端为lettuce
  2. 配置链接的变更
#主要是pool配置的链接参数名称变更
spring.redis.jedis.pool.max-active=300
spring.redis.jedis.pool.max-wait=10000
spring.redis.jedis.pool.max-idle=100
spring.redis.jedis.pool.min-idle=10

3.和spring cache

9.elastic-job

支持2.x
1.包的冲突问题, 冲突主要发生在zookeeper的版本上边
