Apache Camel返回带有转义字符的JSON

import com.fasterxml.jackson.databind.ObjectMapper;

public class MyRouteBuilder extends RouteBuilder {
    @Override
    public void configure() throws Exception {
        from("direct:start")
            .process(exchange -> {
                // 创建JSON对象
                ObjectMapper objectMapper = new ObjectMapper();
                String jsonString = objectMapper.writeValueAsString("带有转义字符的JSON");
                // 设置JSON字符串到消息体中
                exchange.getIn().setBody(jsonString);
            })
            .to("direct:end");
    }
}

import com.google.gson.Gson;
