【Json工具類】json數據格式轉換

在開發中，常用到json數據的轉換，將json格式的字符串與java對象之間的轉換，工具類如下：

import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.core.type.TypeReference;
import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.google.common.collect.Maps;

public class JacksonUtils {
    private static final ObjectMapper om = new ObjectMapper();

    public JacksonUtils() {
    }

    public static String toJson(Object obj) {
        if (obj == null) {
            obj = Maps.newHashMap();
        }

        try {
            return om.writeValueAsString(obj);
        } catch (Exception var2) {
            throw new RuntimeException(var2);
        }
    }

    public static String toPrettyJson(Object obj) {
        if (obj == null) {
            return "";
        } else {
            try {
                return om.writerWithDefaultPrettyPrinter().writeValueAsString(obj);
            } catch (Exception var2) {
                throw new RuntimeException(var2);
            }
        }
    }

    public static <T> T fromJson(String content, Class<T> valueType) {
        try {
            return om.readValue(content, valueType);
        } catch (Exception var3) {
            throw new RuntimeException(var3);
        }
    }

    public static <T> T fromJson(String content, TypeReference typeReference) {
        try {
            return om.readValue(content, typeReference);
        } catch (Exception var3) {
            throw new RuntimeException(var3);
        }
    }

    public static <T> T fromObject(Object obj, Class<T> valueType) {
        try {
            return om.convertValue(obj, valueType);
        } catch (Exception var3) {
            throw new RuntimeException(var3);
        }
    }

    public static <T> T fromObject(Object obj, TypeReference typeReference) {
        try {
            return om.convertValue(obj, typeReference);
        } catch (Exception var3) {
            throw new RuntimeException(var3);
        }
    }

    static {
        om.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        om.setSerializationInclusion(JsonInclude.Include.NON_NULL);
    }
    
}

代碼使用示例：

List<SettlementCreateLogicVo> settlementCreateLogicVoList = JacksonUtils.fromJson(supplierInfoDO.getPurchaseModeInfo(),
                                new TypeReference<List<SettlementCreateLogicVo>>() {
                                });


Map<String, Object> connectDetailAuthInfoMap = JacksonUtils.fromJson(supplierInfoDO.getConnectDetailAuthInfo(), Map.class);



DictDataFeaturesBO featuresBO = JacksonUtils.fromJson(dictDataDO.getFeatures(), DictDataFeaturesBO.class);
