Sonar扫描的NPE问题

直到我修改为这样的代码才通过——


public class DetectorImport {
    public String check1(Nonentity nonentity) {
        String s;
        if(nonentity == null) {
            s = null;
        }else {
            s = nonentity.getName();
        }
        if(s !=null) {
            s = s.replaceAll("（", "(");
        }
        return s;
    }
}

Basic-Javaagent

man java

 -javaagent:jarpath[=options]

Loads the specified Java programming language agent. For more information about instrumenting Java applications, see the java.lang.instrument package description in the Java API documentation at http://docs.oracle.com/javase/8/docs/api/java/lang/instrument/package-summary.html
文档说明部分介绍了基本概念

Provides services that allow Java programming language agents to instrument programs running on the JVM.

Basic-Kafka

link on JianShu

https://kafka.apache.org/quickstart

  • Java8 + Windows环境
  • Zookeeper环境

启动Server时，会提示java.lang.NumberFormatException: For input string: "initial.rebalance.delay.ms"错误，根据这里的提示，在window环境下执行：.\bin\windows\kafka-server-start.bat .\config\server.properties

可以正常启动——这里启动的还是kafka的server，用来连接zookeeper的server，需要先启动zk。否则会超时自动结束。

Basic-Kibana

假装天天接触大数据的样子= =|

Basic的意思就是：了解这个东西是做什么的？如何配置安装？简单实用方法是怎样的？

有了这个概念，就可以上手操作。

SonarQube Continuous code quality made easy.

Start In Two Minute

  1. 下载 SonarQube downloads，使用Sonar qube 7.6版本，Java8支持；最新版本8.0，需要Java 11+
  2. 解压后将bin目录添加到环境变量
  3. 启动SonarQube服务 (默认会使用内置的数据库，可单独配置数据库)
# On Windows, execute:
C:\sonarqube\bin\windows-x86-xx\StartSonar.bat

# On other operating systems, as a non-root user execute:
/opt/sonarqube/bin/[OS]/sonar.sh console

# server log
...

Sonar实践问题记录(一)

jiansh / US

跟踪了一天的问题，记录一下。

问题一：
目前最大的问题为获取Sonar数据时一直处于超时状态。

第一步，怀疑在超时时间内一直请求，相当于对server做了压力测试，导致server端假死。
