引言

最近在做 Sonar 静态代码扫描管理，以此顺手接了 Sonar 的插件开发，基于阿里开发手册进行开发，在整体开发过程中，其中还是遇到不少坑位，也以此给大家做相应借鉴
官网 Demo 演示插件开发地址:
https://docs.sonarqube.org/display/PLUG/Writing+Custom+Java+Rules+101
基于官网的我暂时不多说，基础框架按照官网的范例进行搭建即可

sonar 常用方法说明

范例

需求:【强制】抽象类命名使用 Abstract 或 Base 开头;异常类命名使用 Exception 结尾;测试类 命名以它要测试的类的名称开始，以 Test 结尾。
实现:
AbstractClassNameCheck

package org.finger.java.rule.checks.namerules;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.sonar.check.Rule;
import org.sonar.plugins.java.api.JavaFileScanner;
import org.sonar.plugins.java.api.JavaFileScannerContext;
import org.sonar.plugins.java.api.tree.*;

/**
 * 抽象类命名检查
 * 抽象类命名使用 Abstract 或 Base 开头
 * Created by 古月随笔 on 2017/3/17.
 */
@Rule(key = "AbstractClassNameCheck")
public class AbstractClassNameCheck extends BaseTreeVisitor implements JavaFileScanner{

    private static final Logger LOGGER = LoggerFactory.getLogger(AbstractClassNameCheck.class);

    private JavaFileScannerContext context;

    @Override
    public void scanFile(JavaFileScannerContext context) {
        this.context = context;
        scan(context.getTree());
    }

    @Override
    public void visitClass(ClassTree tree) {
        String className = tree.simpleName().name();

        LOGGER.info(className + "<<>>" + tree.symbol().isAbstract());


        if(tree.symbol().isAbstract()){
            //判断名称是否以Abstract 或 Base 开头

            String abName = "Abstract";
            String bsName = "Base";
            //判断类名如果小于Abstract 或 Base
            if (className.length() < abName.length() || className.length() < bsName.length()) {
                context.reportIssue(this, tree, "The Name Of Abstract Class should use Abstract or Base first");
            } else {
                //判断是否存在 Abstract 或 Base
                if (!className.contains(abName)) {
                    if (!className.contains(bsName)) {
                        context.reportIssue(this, tree, "The Name Of Abstract Class should use Abstract or Base first");
                    } else {
                        if (className.indexOf(bsName) != 0) {
                            context.reportIssue(this, tree, "The Name Of Abstract Class should use Abstract or Base first");
                        }
                    }
                } else {
                    if (className.indexOf(abName) != 0) {
                        context.reportIssue(this, tree, "The Name Of Abstract Class should use Abstract or Base first");
                    }
                }
            }
        }
        super.visitClass(tree);
    }

}

resources 目录下添加目录:org.sonar.l10n.java.rules.squid(这命名主要是由于 sonar 源码中固定写死的)
AbstractClassNameCheck.html

<p>AbstractClassNameCheck Check</p>
<h2>Noncompliant Code Example</h2>
<pre>
    public abstract class HiClass {// Noncompliant
    }

    public abstract class MyNameIsAbstract {// Noncompliant
    }
</pre>
<h2>Compliant Solution</h2>
<pre>
    public abstract class AbstractMysql {
    }

    public abstract class BaseMysql {
    }
</pre>

AbstractClassNameCheck.json

{
  "title": "The Name Of Abstract Class should use Abstract or Base first",
  "status": "ready",
  "remediation": {
    "func": "Constant\/Issue",
    "constantCost": "5min"
  },
  "tags": [
    "bug",
    "pitfall"
  ],
  "defaultSeverity": "CRITICAL"
}

AbstractClassNameCheck_java.json（为什么有这个文件，主要是由于进行单测的时候，sonar 源码内容写死是 xxxx_java.json 命名）

{
  "title": "The Name Of Abstract Class should use Abstract or Base first",
  "status": "ready",
  "remediation": {
    "func": "Constant\/Issue",
    "constantCost": "5min"
  },
  "tags": [
    "bug",
    "pitfall"
  ],
  "defaultSeverity": "CRITICAL"
}

单测：
AbstractClassNameCheckTest

package org.finger.java.rule.checks.namerules;

import org.junit.Test;
import org.sonar.java.checks.verifier.JavaCheckVerifier;

/**
 * Created by huqingen on 2017/3/17.
 */
public class AbstractClassNameCheckTest {
    @Test
    public void test() {
        JavaCheckVerifier.verify("src/test/files/HiClass.java", new AbstractClassNameCheck());
    }

    @Test
    public void test1() {
        JavaCheckVerifier.verify("src/test/files/MyNameIsAbstract.java", new AbstractClassNameCheck());
    }

    @Test
    public void test2() {
        JavaCheckVerifier.verify("src/test/files/BaseMysql.java", new AbstractClassNameCheck());
    }
    @Test
    public void test3() {
        JavaCheckVerifier.verify("src/test/files/AbstractMysql.java", new AbstractClassNameCheck());
    }
}

开发目录结构：

PS：
1.由于编辑的时候经常出现 crash 问题，暂时先写到这，😓，真不是故意
2.编写 sonar 规则的时候，给个建议，采用 Debug 方式调试整个 tree 里面的内容，针对性的编写自己想要的规则，sonar 在这块扫描基础方法做的还是很棒的
