spring - 用 Spring 调试 Jackson

Question

我刚刚在 Spring REST API 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

我找不到错误是什么，错误中没有指定我的文件。有没有办法获得更好的 jackson 错误输出？我知道没有代码你真的帮不上忙，但是有太多的类来把所有的东西都放在这里。

我的 pom.xml 中有 jackson 的这种依赖关系，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

我发现这个使用 Swagger，以 spring mvc 作为服务器类型，我发现错误在由 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“我”

使用者: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: Illegal pattern character 'i'
在 org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate

是 io.swagger.RFC3339DateFormat 的结果

我目前遇到了这个问题，至少删除那条线会给我一个新的和不同的错误......至少它是一个面包屑。
