mvn dependency:tree

2.7.0 2.9.0 衝突

依賴最短路徑優先原則

    一個項目Demo依賴了兩個jar包，其中A-B-C-X(1.0) ， A-D-X(2.0)。由於X(2.0)路徑最短，所以項目使用的是X(2.0)。

pom文件中申明順序優先
如果A-B-X(1.0) ，A-C-X(2.0) 這樣的路徑長度一樣怎麼辦呢？這樣的情況下，maven會根據pom文件聲明的順序加載，如果先聲明瞭B，後聲明瞭C，那就最後的依賴就會是X(1.0)。

覆寫優先

子pom內聲明的優先於父pom中的依賴。

把這個依賴放到pom的最前面，沒好使

redis.clients
jedis
2.9.0

css的！important
div{color:#f00!important;}

剛纔吹噓dependency:tree時，我用到了“無處遁形”，其實有時你會發現簡單地用dependency:tree往往並不能查看到所有的傳遞依賴。不過如果
你真的想要看所有的，必須得加一個-Dverbose參數，這時就必定是最全的了。
全是全了，但顯示出來的東西太多，頭暈目眩，有沒有好法呢？當然有了，加上Dincludes或者Dexcludes說出你喜歡或討厭，dependency:tree就會幫你過濾出來：
引用
Dincludes=org.springframework:spring-tx
過濾串使用groupId:artifactId:version的方式進行過濾，可以不寫全啦，如：

mvn dependency:tree -Dverbose -Dincludes=asm:asm

就會出來asm依賴包的分析信息：

第二板斧:將不想要的傳遞依賴剪除掉

承上，假設我們不希望asm:asm:jar:1.5.3出現，根據分析，我們知道它是經由org.unitils:unitils-dbmaintainer:jar:3.3引入的，
那麼在pom.xml中找到這個依賴，做其它的調整：
mvn dependency:tree -Dverbose -Dincludes=org.apache.commons

<dependency>  
        <groupId>org.unitils</groupId>  
        <artifactId>unitils-dbmaintainer</artifactId>  
        <version>${unitils.version}</version>  
        <exclusions>  
            <exclusion>  
                <artifactId>dbunit</artifactId>  
                <groupId>org.dbunit</groupId>  
            </exclusion>  
            <!-- 這個就是我們要加的片斷 -->  
            <exclusion>  
                <artifactId>asm</artifactId>  
                <groupId>asm</groupId>  
            </exclusion>  
        </exclusions>  
    </dependency>

第三板斧:查看運行期類來源的JAR包

有時，你以爲解決了，但是偏偏還是報類包衝突（典型症狀是java.lang.ClassNotFoundException或Method不兼容等異常），這時你可以設置一個斷點，在
斷點處通過下面這個我做的工具類來查看Class所來源的JAR包：

package com.mtons.mblog.leetcode;

import org.objectweb.asm.ClassVisitor;

import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;
import java.security.CodeSource;
import java.security.ProtectionDomain;

public class ClassLocationUtils {
    /**
     * 獲取類所有的路徑
     *
     * @param cls
     * @return
     */
    public static String where(final Class cls) {
        if (cls == null) throw new IllegalArgumentException("null input: cls");
        URL result = null;
        final String clsAsResource = cls.getName().replace('.', '/').concat(".class");
        final ProtectionDomain pd = cls.getProtectionDomain();
        if (pd != null) {
            final CodeSource cs = pd.getCodeSource();
            if (cs != null) result = cs.getLocation();
            if (result != null) {
                if ("file".equals(result.getProtocol())) {
                    try {
                        if (result.toExternalForm().endsWith(".jar") ||
                                result.toExternalForm().endsWith(".zip"))
                            result = new URL("jar:".concat(result.toExternalForm())
                                    .concat("!/").concat(clsAsResource));
                        else if (new File(result.getFile()).isDirectory())
                            result = new URL(result, clsAsResource);
                    } catch (MalformedURLException ignore) {
                    }
                }
            }
        }
        if (result == null) {
            final ClassLoader clsLoader = cls.getClassLoader();
            result = clsLoader != null ?
                    clsLoader.getResource(clsAsResource) :
                    ClassLoader.getSystemResource(clsAsResource);
        }
        return result.toString();
    }

    public static void main(String[] args) {
        System.out.println(ClassLocationUtils.where(ClassVisitor.class));
    }
}

隨便寫一個測試，設置好斷點，在執行到斷點處按alt+F8動態執行代碼（intelij idea），假設我們輸入：
ClassLocationUtils.where(org.objectweb.asm.ClassVisitor.class)

即可馬上查出類對應的JAR了：

這就是org.objectweb.asm.ClassVisitor類在運行期對應的JAR包，如果這個JAR包版本不是你期望你，就說明是你的IDE緩存造成的，這時建議你
Reimport一下maven列表就可以了，如下所示(idea)：

Reimport一下，IDE會強制根據新的pom.xml設置重新分析並加載依賴類包，以得到和pom.xml設置相同的依賴。（這一步非常重要哦，經常項目組pom.xml是
相同的，但是就是有些人可以運行，有些人不能運行，俗稱人品問題，其實都是IDE的緩存造成的了
idea清除緩存,爲了提高效率不建議採用reimport重新起開啓項目的方式,建議採用idea自帶的功能,File->Invalidate Caches 功能直接完成清除idea cache

成功找到衝突的依賴

        </dependency>

又報錯：
org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is org.springframework.boot.web.serve
r.WebServerException: Unable to start embedded Tomcat

idea 打開pom.xml文件，依次選擇Maven -> Show Dependencies…
樹狀的依賴關係，和dependency:tree命令結果一致，只不過是更形象的圖形化界面。
我的idea是旗艦版，聽說社區版沒有

Caused by: java.lang.NoClassDefFoundError: redis/clients/jedis/util/SafeEncoder
解決辦法:降低redis.clients的版本

com.reachauto.vspcloud vspcloud-component-redis 1.0.0 jedis redis.clients

在這裏插入圖片描述

Caused by: java.lang.NoClassDefFoundError: redis/clients/jedis/util/SafeEncoder
檢查端口號是否啓動
netstat -an|findstr “8999”

最終解決辦法：

<!--添加jedis客戶端-->
<!--<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.9.0</version>
</dependency>-->

修改類
import redis.clients.jedis.util.Pool;

nacos修改配置：

 # feign:
 #   sentinel:
 #     enabled: true
 #     client:
 #       config:
 #         default:
 #           connectTimeout: 2000
 #           readTimeout: 5000

ERROR o.s.d.r.l.RedisMessageListenerContainer[651][GW] - Connection failure occurred. Restarting subscription task after 5000 ms

解決方案：
最後起來是因爲注掉了redis連接的密碼
