我刚刚在 Spring REST API 的多个文件中编写了一些代码，现在出现了 Jackson 错误。

我找不到错误是什么，并且错误中没有指定我的任何文件。有没有办法获得更好的 Jackson 错误输出？我知道如果没有代码你就无法真正提供帮助，但是类太多，无法将所有内容都放在这里。
我的 pom.xml 中有 jackson 的依赖项，我不确定它是哪个版本。
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-joda</artifactId>
</dependency>
我使用 Swagger 发现了这一点，以 spring mvc 作为服务器类型，我发现错误位于由 swagger 生成的
application.propertiesspringfox.documentation.swagger.v2.path=/api-docs
server.contextPath=
server.port=8080
spring.jackson.date-format=io.swagger.RFC3339DateFormat
spring.jackson.serialization.WRITE_DATES_AS_TIMESTAMPS=false
就我而言，错误中的“i”
Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.http.converter.json.Jackson2ObjectMapperBuilder]: Factory method 'jacksonObjectMapperBuilder' threw exception; nested exception is java.lang.IllegalArgumentException: Illegal pattern character 'i'
at org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate
是使用
io.swagger.RFC3339DateFormat我目前遇到这个问题，至少删除该行会给我一个新的不同的错误。至少它是一个面包屑。
我也有类似的问题。就我而言，事实证明日期格式类是在不同的目录中生成的。我必须将 application.properties 中的默认条目更新为
spring.jackson.date-format=com.company.date.RFC3339DateFormat
我相信您的代码在 Jackson2ObjectMapperBuilder 的以下方法中失败。
public Jackson2ObjectMapperBuilder simpleDateFormat(String format) {
this.dateFormat = new SimpleDateFormat(format);
return this;
}
您可以在此方法中放置一个调试器并发布此处传递的格式吗？
这可能是因为该属性未指向生成的 RFC3339DateFormat 类。
摘录供参考。如下所述，RFC3339DateFormat 类位于 com.test.config 中，
package com.test.config;
import java.text.FieldPosition;
import java.util.Date;
import com.fasterxml.jackson.databind.util.ISO8601DateFormat;
import com.fasterxml.jackson.databind.util.ISO8601Utils;
public class RFC3339DateFormat extends ISO8601DateFormat {
private static final long serialVersionUID = 1L;
@Override
public StringBuffer format(Date date, StringBuffer toAppendTo, FieldPosition fieldPosition) {
String value = ISO8601Utils.format(date, true);
toAppendTo.append(value);
return toAppendTo;
}
}
属性文件中的以下条目应指向 com.test.config 下的 RFC3339DateFormat，
spring.jackson.date-format: com.test.config.RFC3339DateFormat
在代码中的某个地方，您拼错了字符“c”。这就是我看到你的错误日志的地方。
