1.增加原因

由于有的时候需要日志打印json，但是如果不格式化输出，json数据很难看，所以就使用这种方式进行json的格式化输出

2.common-tool-starter

1.目录结构

2.JsonUtil.java json工具类

package cn.sunxiansheng.tool.utils;import com.google.gson.Gson;
import com.google.gson.JsonElement;
import com.google.gson.JsonParser;/*** Description: Json工具类** @Author sun* @Create 2025/1/24 18:48* @Version 1.0*/
public class JsonUtil {private final Gson loggingGson;// ANSI 颜色代码 - 绿色private static final String ANSI_GREEN = "\u001B[32m";private static final String ANSI_RESET = "\u001B[0m";// 使用 Spring 注入 loggingGsonpublic JsonUtil(Gson loggingGson) {this.loggingGson = loggingGson;}/*** 格式化打印对象** @param object 任意对象* @return 格式化后的 JSON 字符串（绿色输出）*/public String toPrettyJson(Object object) {if (object == null) {return ANSI_GREEN + "null" + ANSI_RESET;}try {return "\n" + ANSI_GREEN + loggingGson.toJson(object) + ANSI_RESET;} catch (Exception e) {return ANSI_GREEN + "无法格式化对象为 JSON: " + e.getMessage() + ANSI_RESET;}}/*** 格式化打印 JSON 字符串** @param jsonString 原始 JSON 字符串* @return 格式化后的 JSON 字符串（绿色输出）*/public String toPrettyJson(String jsonString) {if (jsonString == null || jsonString.trim().isEmpty()) {return ANSI_GREEN + "空的 JSON 字符串" + ANSI_RESET;}try {JsonElement jsonElement = JsonParser.parseString(jsonString);return "\n" + ANSI_GREEN + loggingGson.toJson(jsonElement) + ANSI_RESET;} catch (Exception e) {return ANSI_GREEN + "无法解析并格式化 JSON 字符串: " + e.getMessage() + ANSI_RESET;}}
}

3.ToolAutoConfiguration.java 自动配置

package cn.sunxiansheng.tool.config;import cn.sunxiansheng.tool.utils.JsonUtil;
import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import lombok.extern.slf4j.Slf4j;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;import javax.annotation.PostConstruct;/*** Description: ToolAutoConfiguration的自动配置类** @Author sunxiansheng* @Create 2025/01/24 18:49* @Version 1.0*/
@Configuration
@Slf4j
public class ToolAutoConfiguration {/*** 自动配置成功日志*/@PostConstructpublic void logConfigSuccess() {log.info("ToolAutoConfiguration has been loaded successfully!");}/*** 配置日志用的 Gson Bean** @return 格式化的 Gson 对象*/@Bean(name = "loggingGson")public Gson loggingGson() {return new GsonBuilder().setPrettyPrinting() // 启用格式化输出.disableHtmlEscaping() // 禁用 HTML 转义.create();}/*** 注入json工具类** @return*/@Beanpublic JsonUtil jsonUtil() {return new JsonUtil(loggingGson());}
}
