记一次云效 流水线 打包 springboog jackson date-format 不生效的问题
事故描述：
期望项目中的日期和前端的交互（输入和输出）使用yyyy-MM-dd HH:mm:ss的格式进行（默认是时间戳）。因此在yml中配置了date-format。同时由于代码中需要忽略前端传入的多余的参数（@RequestBody会报错），因此实现了WebMvcConfigurer类，
设置为可忽略未知属性（查询到资料实现这个类之后，日期格式在yml中配置会失效），随后在代码中设置date-format如下：
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
ObjectMapper objectMapper = converter.getObjectMapper();
//添加此配置
objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
objectMapper.setDateFormat(simpleDateFormat);
converter.setObjectMapper(objectMapper);
//将我们定义的时间格式转换器添加到转换器列表中,
//这样jackson格式化时候但凡遇到Date类型就会转换成我们定义的格式
converters.add(0,converter);
}
本地开发环境表现和期望一致，时间的输入和输出都变成了yyyy-MM-dd HH:mm:ss。但云效发布到服务器的格式仍然是时间戳，字符串格式要报异常：

意思很明确，反正就是配置是没起作用的。
因当时解决后升级了版本，但未修改云效上的发布脚本。导致一直发布的旧版本，所以后面所有的变动都有可能时修复的原因。现记录可能的原因如下：
根据可能性排列（可能性高的排在前面）
1、云效构建步骤中，选择的Maven版本从3.5.2 -> 3.6.3(本地开发版本就是3.6.3，改成和开发版本一致)
2、pom中删除了一些json包：
<!--添加JDBC依赖-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20200518</version>
</dependency>
<dependency>
<groupId>org.dom4j</groupId>
<artifactId>dom4j</artifactId>
<version>2.1.3</version>
</dependency>
<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>2.6</version>
</dependency>
commons-lang 改到 commons-lang3
3、WebMvcConfigurer的实现类，合并成一个（之前由多个，但configureMessageConverters始终只有一个）
同时converters.add(converter) -> converters.add(0,converter);
4、swagger版本从 2.5.0 升级到 2.9.2
