1、添加全局配置类，对时区进行配置

src/main/java/com/cmeeting/config/GlobalConfig.java

+package com.cmeeting.config;
+
+import org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer;
+import org.springframework.context.annotation.Bean;
+import org.springframework.context.annotation.Configuration;
+
+import java.util.TimeZone;
+
+/**
+ * @Description 
+ * @Author zhang kaishi
+ * @Date 2025/7/18 9:27
+ **/
+@Configuration
+public class GlobalConfig {
+
+    /**
+     * 时区配置
+     */
+    @Bean
+    public Jackson2ObjectMapperBuilderCustomizer jacksonObjectMapperCustomization()
+    {
+        return jacksonObjectMapperBuilder -> jacksonObjectMapperBuilder.timeZone(TimeZone.getDefault());
+    }
+}
