Illegal unquoted character ((CTRL-CHAR, code 19))

Restful接口400错误 Illegal unquoted character ((CTRL-CHAR, code 19)): has to be escaped using backslash to be included in string value 解决

此错误与restful框架的json序列化配置有关，例如使用fastjson 可以修改框架默认json解析配置

如jersey框架 增加如下配置:

package com.chanjet.finance.Provider;

import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;

@Provider
public class ObjectMapperProvider implements ContextResolver
{

    final ObjectMapper defaultObjectMapper;

    public ObjectMapperProvider()
    {
        defaultObjectMapper = createDefaultMapper();
    }

    @Override
    public ObjectMapper getContext(final Class type)
    {
        return defaultObjectMapper;
    }

    private static ObjectMapper createDefaultMapper()
    {
        //覆盖jersey默认 json 解析器
        //增加对允许UNQUOTED_CONTROL_CHARS字符
        final ObjectMapper result = new ObjectMapper()
                .configure(JsonParser.Feature.ALLOW_UNQUOTED_CONTROL_CHARS, true);

        result.enable(SerializationFeature.INDENT_OUTPUT);

        return result;
    }
}


//覆盖框架默认的解析器
register(ObjectMapperProvider.class);
// Jackson JSON marshalling
register(JacksonFeature.class);

fastjson其他序列话属性：

        AUTO_CLOSE_SOURCE(true),
        ALLOW_COMMENTS(false),
        ALLOW_YAML_COMMENTS(false),
        ALLOW_UNQUOTED_FIELD_NAMES(false),
        ALLOW_SINGLE_QUOTES(false),
        ALLOW_UNQUOTED_CONTROL_CHARS(false),
        ALLOW_BACKSLASH_ESCAPING_ANY_CHARACTER(false),
        ALLOW_NUMERIC_LEADING_ZEROS(false),
        ALLOW_NON_NUMERIC_NUMBERS(false),
        STRICT_DUPLICATE_DETECTION(false);
