spring boot +dubbo 踩坑记录

今天初次搭建spring boot +duboo的demo.记录一下踩坑记录。

　　首先搭建3个小demo,一个maven项目，两个spring boot （服务提供者和服务消费者）项目。

　　两 spring boot 引入jar:

<!--引入dubbo的依赖-->
<dependency>
<groupId>com.alibaba.spring.boot</groupId>
<artifactId>dubbo-spring-boot-starter</artifactId>
<version>2.0.0</version>
</dependency>
<!-- 引入zookeeper的依赖 -->
<dependency>
<groupId>com.101tec</groupId>
<artifactId>zkclient</artifactId>
<version>0.10</version>
</dependency>

整合时spring boot和zookeeper报一个不兼容jar包的错，spring boot本身内含slf4j日志框架，zookeeper 也提供slf4j.jar 。

1.解决方案 pom.xml替换jar包

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <exclusions>
                <exclusion>
                  <groupId>org.springframework.boot</groupId>
                  <artifactId>spring-boot-starter-logging</artifactId>
                </exclusion>
              </exclusions>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
              <exclusions>
                <exclusion>
                  <groupId>org.springframework.boot</groupId>
                  <artifactId>spring-boot-starter-logging</artifactId>
               </exclusion>
         </exclusions>
</dependency>
2.解决方案 pom.xml替换

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
                <exclusion>
                    <groupId>ch.qos.logback</groupId>
                   <artifactId>logback-classic</artifactId>
                </exclusion>
           </exclusions>
</dependency>
3.解决方案 pom,xml替换

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <!--排除这个slf4j-log4j12-->
    <exclusions>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
        </exclusion>
    </exclusions>
</dependency>

<dependency>
    <groupId>org.apache.zookeeper</groupId>
    <artifactId>zookeeper</artifactId>
    <version>3.4.8</version>
    <!--排除这个slf4j-log4j12-->
    <exclusions>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
        </exclusion>
    </exclusions>
</dependency>

4.解决方案
将maven仓库中的关于打印日志的jar删除
就是将 .m2/repository/org/slf4j下的slf4j-log4j12文件删除 。
