Question

我刚刚在Spring REST API中的多个文件中编写了一些代码，现在我遇到了Jackson错误。

org.springframework.context.ApplicationContextException: Unable to start 

embedded container; nested exception is

我无法找到错误，错误中未指定任何文件。有没有办法获得更好的杰克逊错误输出？我知道如果没有代码你就无法提供帮助，但是有太多的课程可以把所有内容放在这里。

我在我的pom.xml中对jackson有这种依赖关系，我不确定它是哪个版本。

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-joda</artifactId>
 </dependency>

Answer 1

我发现这是使用Swagger，使用spring mvc作为服务器类型，我发现错误是在swagger生成的application.properties中...

springfox.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

在我的情况下，错误中的'i'

aused by：org.springframework.beans.BeanInstantiationException：无法实例化[org.springframework.http.converter.json.Jackson2ObjectMapperBuilder]：工厂方法'jacksonObjectMapperBuilder'抛出异常;嵌套异常是java.lang.IllegalArgumentException：非法模式字符'i' 在org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate

是io.swagger.RFC3339DateFormat

的结果

我目前遇到这个问题，至少删除该行会给我一个新的不同错误...至少它是一个面包屑。

Answer 2

我有一个类似的问题。就我而言，事实证明日期格式类是在另一个目录中生成的。我必须将application.properties中的默认条目更新为

spring.jackson.date-format=com.company.date.RFC3339DateFormat

Answer 3

在代码的某个地方，你拼错了字符＆＃39; c＆＃39;。那是我看到你的错误日志的地方。

Answer 4

我相信你的代码在Jackson2ObjectMapperBuilder的以下方法中失败了。

public Jackson2ObjectMapperBuilder simpleDateFormat(String format) {
        this.dateFormat = new SimpleDateFormat(format);
        return this;
    }

您可以在此方法中放置调试器并发布此处传递的格式吗？

Answer 5

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

用Spring调试Jackson
