Java 编写查看调用栈信息

大家在开发项目的过程中，应该经常会需要分析调用栈信息，所以这里提供一个调用栈打印工具类，大家拿去直接用就行了

import java.io.ByteArrayOutputStream;
import java.io.PrintStream;

public class StringLogUtils {
    public static String printStackTrace(Throwable throwable) {
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        PrintStream ps = new PrintStream(bos);
        String result = null;
        try {
            throwable.printStackTrace(ps);
            result = bos.toString();
        } finally {
            try {
                ps.close();
            } catch (Exception e) {

            }
        }
        return result;
    }

    public static String printStackTrace(Thread thread, boolean keepCallingFunction) {
        StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append("Thread: " + thread.getName() + ", id: " + thread.getId() + ", Group: " + thread.getThreadGroup().getName() + ", state: " + thread.getState())
                .append("\n");
        int index = 2;
        if (!keepCallingFunction) {
            index++;
        }
        StackTraceElement[] trace = thread.getStackTrace();
        for (; index < trace.length; index++) {
            StackTraceElement traceElement = trace[index];
            stringBuilder.append("\tat " + traceElement)
                    .append("\n");
        }
        return stringBuilder.toString();
    }

    public static String printStackTrace(Thread thread) {
        return printStackTrace(thread, false);
    }

    public static String printStackTrace() {
        return printStackTrace(Thread.currentThread(), false);
    }

    public static String splitUrl(String url, String split, int index) {
        try {
            String[] arr = url.split(split);
            return arr[index];
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

}
