Apache驼峰休息服务,带有底部和北欧字母

标签: apache-camel wildfly undertow

我有一个使用underow componentsnet的休息服务。我使用wildfly和wildfly补丁4.7.0(apache camel 2.19)

我有问题要回复我的Rest服务的北欧字母。与邮递员一起测试。

代码是:

 @Override
    public void configure() throws Exception {
        restConfiguration().component("undertow");
        rest("/hello").post("/{name}").consumes("application/json").to("direct:testpost");
        from("direct:testpost")
                .routeId("testpost")
                .log("${body}")
                .transform().jsonpath("test");
    }

当我发送时:

  

POST / hello / Anton HTTP / 1.1主机:192.168.56.103:8080内容类型:   application / json; charset = UTF-8 Cache-Control:no-cache   邮差 - 令牌:c7ed9034-8b58-d104-9804-a1ff60a26f65

     

{“test”:“用Å测试”}

我收到错误:

  

2017-06-07 07:06:16,253 INFO [testput](默认任务-5){“test”:   “用Å测试}}

所以有任何想法如何解决这个问题?所有帮助表示赞赏!

答案 0 :(得分:0)

这是org.apache.camel.converter.NIOConverter(2.18.4)中的错误

public static ByteBuffer toByteBuffer(String value, Exchange exchange) {
    ByteBuffer buf = ByteBuffer.allocate(value.length());
    byte[] bytes = null;
    if (exchange != null) {
        String charsetName = exchange.getProperty(Exchange.CHARSET_NAME, String.class);
        if (charsetName != null) {
            try {
                bytes = value.getBytes(charsetName);
            } catch (UnsupportedEncodingException e) {
                LOG.warn("Cannot convert the byte to String with the charset " + charsetName, e);
            }
        }
    }
    if (bytes == null) {
        bytes = value.getBytes();
    }
    buf.put(bytes);
    buf.flip();
    return buf;
}

ByteBuffer使用String.length()进行分配,忽略了它可能包含双字节字符的事实。

我正在通过使用eventlistener替换注册表中的转换器来解决此错误。

void onContextStarting(@Observes CamelContextStartingEvent event) {
    def context = event.getContext();
    def registry = context.getTypeConverterRegistry();

    registry.setTypeConverterExistsLoggingLevel(LoggingLevel.INFO)
    registry.setTypeConverterExists(TypeConverterExists.Override)
    registry.addTypeConverter(ByteBuffer.class,String.class, new StringToByteBufferConverter());
    registry.setTypeConverterExists(TypeConverterExists.Ignore)
}

我替换它的转换器使用byte.length来分配ByteBuffer,因此缓冲区匹配字符串的实际字节数:

import org.apache.camel.Exchange;
import org.apache.camel.support.TypeConverterSupport;

import java.io.UnsupportedEncodingException;
import java.nio.ByteBuffer;

public class StringToByteBufferConverter extends TypeConverterSupport {

  public <T> T convertTo(Class<T> type, Exchange exchange, Object object) {
    String value = (String)object;
    byte[] bytes = null;
    if (exchange != null) {
        String charsetName = exchange.getProperty(Exchange.CHARSET_NAME, String.class);
        if (charsetName != null) {
            try {
                bytes = value.getBytes(charsetName);
            } catch (UnsupportedEncodingException e) {
                throw new UnsupportedOperationException(e);
            }
        }
    }
    if (bytes == null) {
        bytes = value.getBytes();
    }
    ByteBuffer buf = ByteBuffer.allocate(bytes.length);
    buf.put(bytes);
    buf.flip();
    return (T)buf;
  }

}

您还可以通过将主体转换为String以外的类型来绕过这个错误来绕过坏转换器:

@Override
public void configure() throws Exception {
    restConfiguration().component("undertow");
    rest("/hello").post("/{name}").consumes("application/json").to("direct:testpost");
    from("direct:testpost")
            .routeId("testpost")
            .log("${body}")
            .transform().jsonpath("test")
            .convertBodyTo(byte[].class);
}
