sonar findbugs plugin源码研究

首先贴一下findbugs plugin 代码目录：

代码：

sonar findbugs plugin源码研究_第3张图片

代码里面有很几个关于plugin定义的关键类：

language包下面定义了扫描jsp 的思路：

public class Jsp
  extends AbstractLanguage
{
  public static final String KEY = "jsp";
  public static final String NAME = "JSP";
  public static final String FILE_SUFFIXES_KEY = "sonar.jsp.file.suffixes";
  public static final String DEFAULT_FILE_SUFFIXES = ".jsp";
  private final Settings settings;
  
  public Jsp(Settings settings)
  {
    super("jsp", "JSP");
    this.settings = settings;
  }
  
  public String[] getFileSuffixes()
  {
    String[] suffixes = filterEmptyStrings(this.settings.getStringArray("sonar.jsp.file.suffixes"));
    if (suffixes.length == 0) {
      suffixes = StringUtils.split(".jsp", ",");
    }
    return suffixes;
  }
  
  private static String[] filterEmptyStrings(String[] stringArray)
  {
    List nonEmptyStrings = Lists.newArrayList();
    for (String string : stringArray) {
      if (StringUtils.isNotBlank(string.trim())) {
        nonEmptyStrings.add(string.trim());
      }
    }
    return (String[])nonEmptyStrings.toArray(new String[nonEmptyStrings.size()]);
  }
}

JspCodeColorizerFormat 类定义了如何识别标签扫描jsp

public class JspCodeColorizerFormat
  extends CodeColorizerFormat
{
  private final List tokenizers = new ArrayList();
  
  public JspCodeColorizerFormat()
  {
    super("jsp");
    String tagAfter = "";
    

    this.tokenizers.add(new RegexpTokenizer("", tagAfter, "?"));
    this.tokenizers.add(new RegexpTokenizer("", tagAfter, ">"));
    

    this.tokenizers.add(new RegexpTokenizer("", tagAfter, ""));
    

    this.tokenizers.add(new MultilinesDocTokenizer("", "", tagAfter));
    this.tokenizers.add(new MultilinesDocTokenizer("<%--", "--%>", "", tagAfter));
    

    this.tokenizers.add(new MultilinesDocTokenizer("<%@", "%>", "", tagAfter));
    this.tokenizers.add(new MultilinesDocTokenizer("<%", "%>", "", tagAfter));
    

    this.tokenizers.add(new StringTokenizer("", tagAfter));
  }
  
  public List getTokenizers()
  {
    return this.tokenizers;
  }
}

profiles 包中定义了规则相关：

FindBugs + FB-Contrib 规则，针对语言java

public class FindbugsContribProfile
  extends ProfileDefinition
{
  private static final String FB_CONTRIB_PROFILE_NAME = "FindBugs + FB-Contrib";
  private final FindbugsProfileImporter importer;
  
  public FindbugsContribProfile(FindbugsProfileImporter importer)
  {
    this.importer = importer;
  }
  
  public RulesProfile createProfile(ValidationMessages messages)
  {
    Reader findbugsProfile = new InputStreamReader(getClass().getResourceAsStream("/org/sonar/plugins/findbugs/profile-findbugs-and-fb-contrib.xml"));
    
    RulesProfile profile = this.importer.importProfile(findbugsProfile, messages);
    profile.setLanguage("java");
    profile.setName("FindBugs + FB-Contrib");
    return profile;
  }
}

定义FindBugs 规则，针对语言java

public class FindbugsProfile
  extends ProfileDefinition
{
  private static final String FINDBUGS_PROFILE_NAME = "FindBugs";
  private final FindbugsProfileImporter importer;
  
  public FindbugsProfile(FindbugsProfileImporter importer)
  {
    this.importer = importer;
  }
  
  public RulesProfile createProfile(ValidationMessages messages)
  {
    Reader findbugsProfile = new InputStreamReader(getClass().getResourceAsStream("/org/sonar/plugins/findbugs/profile-findbugs-only.xml"));
    
    RulesProfile profile = this.importer.importProfile(findbugsProfile, messages);
    profile.setLanguage("java");
    profile.setName("FindBugs");
    return profile;
  }
}

定义了规则FindBugs Security Audit，针对语言java

public class FindbugsSecurityAuditProfile
  extends ProfileDefinition
{
  private static final String FINDBUGS_SECURITY_AUDIT_PROFILE_NAME = "FindBugs Security Audit";
  private final FindbugsProfileImporter importer;
  
  public FindbugsSecurityAuditProfile(FindbugsProfileImporter importer)
  {
    this.importer = importer;
  }
  
  public RulesProfile createProfile(ValidationMessages messages)
  {
    Reader findbugsProfile = new InputStreamReader(getClass().getResourceAsStream("/org/sonar/plugins/findbugs/profile-findbugs-security-audit.xml"));
    
    RulesProfile profile = this.importer.importProfile(findbugsProfile, messages);
    profile.setLanguage("java");
    profile.setName("FindBugs Security Audit");
    return profile;
  }
}

定义检查规则FindBugs Security JSP 针对语言：jsp

public class FindbugsSecurityJspProfile
  extends ProfileDefinition
{
  private static final String FINDBUGS_SECURITY_JSP_PROFILE_NAME = "FindBugs Security JSP";
  private final FindbugsProfileImporter importer;
  
  public FindbugsSecurityJspProfile(FindbugsProfileImporter importer)
  {
    this.importer = importer;
  }
  
  public RulesProfile createProfile(ValidationMessages messages)
  {
    Reader findbugsProfile = new InputStreamReader(getClass().getResourceAsStream("/org/sonar/plugins/findbugs/profile-findbugs-security-jsp.xml"));
    
    RulesProfile profile = this.importer.importProfile(findbugsProfile, messages);
    profile.setLanguage("jsp");
    profile.setName("FindBugs Security JSP");
    return profile;
  }

定义规则：FindBugs Security Minimal 针对语言java

public class FindbugsSecurityMinimalProfile
  extends ProfileDefinition
{
  private static final String FINDBUGS_SECURITY_AUDIT_PROFILE_NAME = "FindBugs Security Minimal";
  private final FindbugsProfileImporter importer;
  
  public FindbugsSecurityMinimalProfile(FindbugsProfileImporter importer)
  {
    this.importer = importer;
  }
  
  public RulesProfile createProfile(ValidationMessages messages)
  {
    Reader findbugsProfile = new InputStreamReader(getClass().getResourceAsStream("/org/sonar/plugins/findbugs/profile-findbugs-security-minimal.xml"));
    
    RulesProfile profile = this.importer.importProfile(findbugsProfile, messages);
    profile.setLanguage("java");
    profile.setName("FindBugs Security Minimal");
    return profile;
  }
}

xml 包中定义一些规则相关的bean

FindbugsPlugin 定义类：

    context.addExtensions(Arrays.asList(new Class[] { Jsp.class, JspCodeColorizerFormat.class, FindbugsSensor.class, FindbugsConfiguration.class, FindbugsExecutor.class, FindbugsProfileExporter.class, FindbugsProfileImporter.class, FindbugsProfile.class, FindbugsContribProfile.class, FindbugsSecurityAuditProfile.class, FindbugsSecurityMinimalProfile.class, FindbugsSecurityJspProfile.class, FindbugsRulesDefinition.class, FbContribRulesDefinition.class, FindSecurityBugsRulesDefinition.class, FindSecurityBugsJspRulesDefinition.class, ByteCodeResourceLocator.class }));

加载各种定义的 profile类，然后就是FindbugsProfileExporter和FindbugsProfileImporter，规则文件的到处生产和规则文件的导入类：

首个字符必须为字母（a-z，A-Z） 
中间不能有空格，可以使用下划线（_） 
不能使用标点符号 
不能使用bash里的关键字（可用help命令查看保留关键字）

1.1、什么是lucene 
    Lucene是一个全文搜索框架，而不是应用产品。因此它并不像baidu或者googleDesktop那种拿来就能用，它只是提供了一种工具让你能实现这些产品和功能。 
1.2、lucene能做什么 
    要回答这个问题，先要了解lucene的本质。实际

    不论你是想自己设计游戏，还是开发iPhone或安卓手机上的应用，还是仅仅为了娱乐，学习编程语言都是一条必经之路。编程语言种类繁多，用途各 异，然而一旦掌握其中之一，其他的也就迎刃而解。作为初学者，你可能要先从Java或HTML开始学，一旦掌握了一门编程语言，你就发挥无穷的想象，开发 各种神奇的软件啦。 
1、确定目标 
学习编程语言既充满乐趣，又充满挑战。有些花费多年时间学习一门编程语言的大学生到

javaC++finalize()堆栈内存回收
                                    
    大家知道， Java 除了那 8 种基本类型以外，其他都是对象类型（又称为引用类型）的数据。 JVM 会把程序创建的对象存放在堆空间中，那什么又是堆空间呢？其实，堆（ Heap）是一个运行时的数据存储区，从它可以分配大小各异的空间。一般，运行时的数据存储区有堆（ Heap）和堆栈（ Stack），所以要先看它们里面可以分配哪些类型的对象实体，然后才知道如何均衡使用这两种存储区。一般来说，栈中存放的

    一、程序的组成部分   　　Linux下程序大都是由以下几部分组成：   　　二进制文件：也就是可以运行的程序文件   　　库文件：就是通常我们见到的lib目录下的文件   　　配置文件：这个不必多说，都知道   　　帮助文档：通常是我们在linux下用man命令查看的命令的文档   　　 
二、linux下程序的存放目录   　　linux程序的存放目录大致有三个地方：   　　/etc, /b

2007年从学校毕业，凭借自己原创的ASP毕业设计，以为自己很厉害似的，信心满满去东莞找工作，找面试成功率确实很高，只是工资不高，但依旧无法磨灭那过分的自信，那时候什么考勤系统、什么OA系统、什么ERP，什么都觉得有信心，这样的生涯大概持续了约一年。
