两个检测的实现代码，放在这里，因为自己做，没按照标准来

1.列不可超过120

public class ColumnTooLongRule extends AbstractAliRule {

    private static final int MAX_COLUMN_COUNT = 120;


    @Override
    public Object visit(ASTCompilationUnit node, Object data) {
        try {
            int endLine = node.getEndLine();
            if (endLine <= 0) {
                return super.visit(node, data);
            }
            List<Node> childrenNodes = node.findChildNodesWithXPath("//*[@EndColumn > 120]");
            Map<Integer, Node> columnKeyWithNodeValue = this.newHashMap(endLine);
            for (Node childNode : childrenNodes) {
                int endColumn = childNode.getEndColumn();
                if (columnKeyWithNodeValue.containsKey(endColumn)) {
                    continue;
                }
                if (endColumn <= MAX_COLUMN_COUNT) {
                    continue;
                }
                addViolationWithMessage(data, childNode, "java.other.ColumnTooLongRule.rule.msg");
                columnKeyWithNodeValue.put(endColumn, childNode);
            }
        } catch (JaxenException e) {
            e.printStackTrace();
        }
        return super.visit(node, data);
    }

    private <K, V> HashMap<K, V> newHashMap(int size) {
        int capacity = (int)(size/0.75F) + 1;
        return new HashMap<>(capacity);
    }
}

2. 可变参数定义

public class VarargsParameterRule extends AbstractXpathRule {
    private static final String XPATH = "//FormalParameter[@Varargs = 'true' and ./Type[@TypeImage = 'Object']]";

    public VarargsParameterRule() {
        setXPath(XPATH);
    }

    @Override
    public void addViolation(Object data, Node node, String arg) {
        ViolationUtils.addViolationWithPrecisePosition(this, node, data,
                I18nResources.getMessage("java.other.VarargsParameterRule.rule.msg",
                        node.getImage()));
    }

}

再添加一个equals和hashCode必须同时override

   @Override
    public Object visit(ASTCompilationUnit rootNode, Object data) {

        try {
            List<Node> nodeList = rootNode.findChildNodesWithXPath(
                    "//ClassOrInterfaceBodyDeclaration[./Annotation[@AnnotationName = 'Override']]" +
                            "//MethodDeclaration[@MethodName = 'hashCode' or @MethodName = 'equals']");
            if (nodeList.size() == 1) {
                addViolationWithMessage(data, nodeList.get(0),
                        "vivo.java.other.EqualsHashCodeRule.rule.msg");
            }
        } catch (JaxenException e) {
            e.printStackTrace();
        }
        return super.visit(rootNode, data);
    }

谢谢，第一条规则暂不适合进行扫描，第二三条，请走PR流程。
