我从githud存储库中提取最新代码后得到以下内容.

为org.codehaus.mo构建有效模型时遇到的问题

错误的完整描述如下.

在构建有效模型时遇到了1个问题

org.codehaus.mojo:aspectj-maven-plugin:1.8
[ERROR] 'dependencies.dependency.systemPath' for com.sun:tools:jar must specify an absolute path but is ${toolsjarSystemPath} @ 

我使用的是java1.8和sts 3.6.4

我正在使用杰克逊2.x进行序列化和反序列化。我将objectMapper注册到afterBurner模块，并配置了对象映射器以忽略未知属性

objectMapper.registerModule(new AfterBurnerModule());
objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

但是，当它尝试序列化对象时，它会失败，并发现属性错误的未知字段

java对象也用@JsonIgnoreProperties注释（ignoreUnknown = true）

有人可以帮助我了解可能出了什么问题吗

以下是实用程序类

package example;

import com.fasterxml.jackson.annotation.JsonInclude.Include;
import com.fasterxml.jackson.databind.AnnotationIntrospector;
import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.introspect.JacksonAnnotationIntrospector;
import com.fasterxml.jackson.module.afterburner.AfterburnerModule;
import com.fasterxml.jackson.module.jaxb.JaxbAnnotationIntrospector;

public final class Util {
    private static ObjectMapper objectMapper;

    static {
        objectMapper = new ObjectMapper();
        objectMapper.registerModule(new AfterburnerModule());
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
        objectMapper.setDateFormat(sdf);
        objectMapper.setAnnotationIntrospector(AnnotationIntrospector.pair(new JaxbAnnotationIntrospector(objectMapper.getTypeFactory()), new JacksonAnnotationIntrospector()));
        objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        objectMapper.setSerializationInclusion(Include.NON_NULL);

    }

    private Util() {
    }

    public static <T> T convertToObject(String jsonString,Class<T> classType){
        T obj = null;
        try {
            obj = objectMapper.readValue(jsonString, classType);
        } …
