I compare two project ,looks like the serialize way is different

vincentlauvlwj · 2019-08-16T12:22:21Z

You need to configure KtormModule as a Spring managed bean so that the default ObjectMapper in the Spring's container can find and register it.

See KtormConfiguration (line 25) class in ktorm-example-spring-boot.

JsonSong89 · 2019-08-18T05:15:46Z

@vincentlauvlwj
but I have already config the bean, which complete copy from ktorm-example-spring-boot.

JsonSong89 · 2019-08-18T05:37:26Z

print the beans

   val cls = ctx.getBeansOfType(Module::class.java)
   cls.forEach { (k, v) -> println(v.javaClass) }

my project:
class me.liuwj.ktorm.jackson.KtormModule
class springfox.documentation.swagger2.configuration.Swagger2JacksonModule
class com.fasterxml.jackson.module.paramnames.ParameterNamesModule
class org.springframework.boot.jackson.JsonComponentModule

example:
class me.liuwj.ktorm.jackson.KtormModule
class com.fasterxml.jackson.module.paramnames.ParameterNamesModule
class org.springframework.boot.jackson.JsonComponentModule

vincentlauvlwj · 2019-08-18T05:55:56Z

检查一下你项目中是否存在自己定义的 HttpMessageConverter 的 bean，接管了 Spring 默认的 json 序列化过程

JsonSong89 · 2019-08-18T06:17:34Z

哦可以用中文啊哈哈.

我之前用的是fastjson 但也已经注释掉了

vincentlauvlwj · 2019-08-18T06:35:47Z

你可以试一下把这整个类删掉看看

JsonSong89 · 2019-08-18T06:40:03Z

@vincentlauvlwj 去掉@configuration后可以正常序列化了.
但我的跨域,swagger,权限校验拦截器都在这里啊
有办法像fastjson那样显示的声明用ktorm来处理吗?我看了下,貌似没有HttpMessageConverter的实现.

vincentlauvlwj · 2019-08-18T06:51:50Z

自己添加一个 converter 也就两三行代码：

override fun configureMessageConverters(converters: MutableList<HttpMessageConverter<*>>) {
    super.configureMessageConverters(converters)

    converters += MappingJackson2HttpMessageConverter().apply {
        objectMapper = ObjectMapper().registerModule(KtormModule())
    }
}
