以XML或JSON格式输出Java堆栈跟踪

Question

标准堆栈跟踪格式适用于人类。 如何以XML/JSON等结构化格式输出Java堆栈跟踪以供机器使用？

Answer 1

你可以做

package stack43542547; 

import java.io.StringWriter; 
import org.junit.Test; 
import com.fasterxml.jackson.databind.ObjectMapper; 
import com.fasterxml.jackson.databind.SerializationFeature; 

public class HowToConvertStackTraceToJson { 
    @Test 
    public void convertStackTraceToJson() throws Exception { 
     try { 
      throw new NullPointerException(); 
     } catch (Exception e) { 
      System.out.println(asJson(e)); 
     } 
    } 

    private String asJson(Object obj) throws Exception { 
      StringWriter w = new StringWriter(); 
      new ObjectMapper().configure(SerializationFeature.INDENT_OUTPUT, true).writeValue(w, obj); 
      String result = w.toString(); 
      return result; } 
} 

给人
