### 自定义PMD检测的类型集合 ###

*  PMD所能检测的类型（八大种）
 *  使用方法
 *   *  使用xml配置文件配置多条规则
     *   *  1、在resources目录下写个配置文件 settings.xml(命名无要求)
         *  2、configuration.setRuleSets("settings.xml"); 引用规则集
     *  使用setRuleSets配置多条规则

# PMD所能检测的类型（八大种） #

**官网链接：[点这里][Link 1]**

**大概共有319条小规则（不算舍弃的规则）**

**源码包中检测Java的规则所在的位置：`pmd-src-6.32.0\pmd-java\src\main\resources\category\java`**

> **category/java/XXX.xml/xxxxx**

*  **[Best Practices][]：Rules which enforce generally accepted best practices.**
    
     *  **执行普遍接受的最佳做法的规则。**
 *  **[Code Style][]：Rules which enforce a specific coding style.**
    
     *  **执行特定编码样式的规则。**
 *  **[Design][]：Rules that help you discover design issues.**
    
     *  **帮助您发现设计问题的规则。**
 *  **[Documentation][]：Rules that are related to code documentation.**
    
     *  **与代码文档相关的规则。**
 *  **[Error Prone][]：Rules to detect constructs that are either broken, extremely confusing or prone to runtime errors.**
    
     *  **用于检测结构的规则，这些构造要么被破坏，要么非常混乱，或者容易出现运行时错误。**
 *  **[Multithreading][]：Rules that flag issues when dealing with multiple threads of execution.**
    
     *  **在处理多个执行线程时标记问题的规则。**
 *  **[Performance][]：Rules that flag suboptimal code.**
    
     *  **标记次优代码的规则。**
 *  **[Security][]：Rules that flag potential security flaws.**
    
     *  **标记潜在安全漏洞的规则。**

**还有一个快速检测的规则集的源码所在的位置：`pmd-src-6.32.0\pmd-java\src\main\resources\rulesets\java`**

> **rulesets/java/quickstart.xml**

*  **[Additional rulesets][]：附加规则集**
    
    **quickstart (`rulesets/java/quickstart.xml`)**
    
    **PMD的快速启动配置。包括最有可能适用于任何地方的规则。**

# 使用方法 #

## 使用xml配置文件配置多条规则 ##

### 1、在resources目录下写个配置文件 settings.xml(命名无要求) ###

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80Mzg4MzkxNw_size_16_color_FFFFFF_t_70_pic_center]  
**settings.xml：**

<?xml version="1.0"?>
    <ruleset name="myruleset" xmlns="http://pmd.sourceforge.net/ruleset/2.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://pmd.sourceforge.net/ruleset/2.0.0 https://pmd.sourceforge.io/ruleset_2_0_0.xsd">
        <description>My ruleset</description>
    
        <rule ref="category/java/codestyle.xml">
            <exclude name="WhileLoopsMustUseBraces"/>
            <exclude name="IfElseStmtsMustUseBraces"/>
        </rule>
        <rule ref="category/java/performance.xml"></rule>
        <rule ref="category/java/bestpractices.xml"/>
        
        <rule name="myrule" language="java" message="不能有变量为keafmd的String类型的变量" class="net.sourceforge.pmd.lang.rule.XPathRule">
            <description>
                自定义规则
            </description>
            <priority>3</priority>
            <properties>
                <property name="version" value="2.0"/>
                <property name="xpath">
                    <value>
                        <![CDATA[ //VariableDeclaratorId[@Image = "keafmd" and ../../Type[@TypeImage = "String"]] ]]>
                    </value>
                </property>
            </properties>
        </rule>
    
    
        
    
    </ruleset>

### 2、configuration.setRuleSets(“settings.xml”); 引用规则集 ###

package com.keafmd;
    
    import net.sourceforge.pmd.PMD;
    import net.sourceforge.pmd.PMDConfiguration;
    
    import java.util.UUID;
    
    
    /** * Keafmd * * @ClassName: PmdExample * @Description: * @author: 牛哄哄的柯南 * @Date: 2021-03-22 15:01 * @Blog: https://keafmd.blog.csdn.net/ */
    public class PmdExample { 
        public static void main(String[] args) { 
            /*PMDConfiguration configuration = new PMDConfiguration(); configuration.setInputPaths("D:/javaworkspace/pdm-test04/src/main/java/com/keafmd/test01"); configuration.setRuleSets("rulesets/java/quickstart.xml"); configuration.setReportFormat("html"); configuration.setReportFile("D:/pmdreport/pmd-report.html"); PMD.doPMD(configuration);*/
    
            String fileName ;
            // 重新生成文件名（根据具体情况生成对应文件名）
            fileName = UUID.randomUUID()+"_"+"pmd-report.html";
    
            PMDConfiguration configuration = new PMDConfiguration();
            configuration.setInputPaths("D:\\javaworkspace\\pmd-test04\\src\\main\\java\\com\\keafmd\\test01\\Test01.java");
            //configuration.setRuleSets("rulesets/java/quickstart.xml");
            //configuration.setRuleSets("src/main/java/com/keafmd/pmd/myrule.xml");
            configuration.setRuleSets("settings.xml");
            configuration.setReportFormat("html");
            configuration.setReportFile("D:/pmdreport/"+fileName);
    
            PMD.doPMD(configuration);
        }
    
    }

## 使用setRuleSets配置多条规则 ##

**例如：**

configuration.setRuleSets("category/java/bestpractices.xml");
    configuration.setRuleSets("category/java/codestyle.xml");

**完整代码：**

package com.keafmd;
    
    import net.sourceforge.pmd.PMD;
    import net.sourceforge.pmd.PMDConfiguration;
    
    import java.util.UUID;
    
    
    /** * Keafmd * * @ClassName: PmdExample * @Description: * @author: 牛哄哄的柯南 * @Date: 2021-03-22 15:01 * @Blog: https://keafmd.blog.csdn.net/ */
    public class PmdExample { 
        public static void main(String[] args) { 
            /*PMDConfiguration configuration = new PMDConfiguration(); configuration.setInputPaths("D:/javaworkspace/pdm-test04/src/main/java/com/keafmd/test01"); configuration.setRuleSets("rulesets/java/quickstart.xml"); configuration.setReportFormat("html"); configuration.setReportFile("D:/pmdreport/pmd-report.html"); PMD.doPMD(configuration);*/
    
            String fileName ;
            // 重新生成文件名（根据具体情况生成对应文件名）
            fileName = UUID.randomUUID()+"_"+"pmd-report.html";
    
            PMDConfiguration configuration = new PMDConfiguration();
            configuration.setInputPaths("D:\\javaworkspace\\pmd-test04\\src\\main\\java\\com\\keafmd\\test01\\Test01.java");
            //configuration.setRuleSets("rulesets/java/quickstart.xml");
            //configuration.setRuleSets("src/main/java/com/keafmd/pmd/myrule.xml");
            //configuration.setRuleSets("settings.xml");
            configuration.setRuleSets("category/java/bestpractices.xml");
            configuration.setRuleSets("category/java/codestyle.xml");
            configuration.setReportFormat("html");
            configuration.setReportFile("D:/pmdreport/"+fileName);
    
            PMD.doPMD(configuration);
        }
    
    }
