ureport2预览sql时间格式化错误

内容目录

ureport2用的是jackson1.x,那时候貌似还没有java8,但是现在的项目都是基于jdk8做的,所以格式化时间的时候,如果是LocalDateTime是格式化有问题的,返回的是对象类型。
我尝试过用jackson2.x的版本,结果格式化xml的时候会报错,然后我就直接换了fastjson,完美解决问题。

1.ureport2-console添加依赖

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.76</version>
</dependency>

2.修改WriteJsonServletAction

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.serializer.SerializerFeature;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.OutputStream;

/**

public abstract class WriteJsonServletAction extends BaseServletAction {
    protected void writeObjectToJson(HttpServletResponse resp, Object obj) throws ServletException, IOException {
        resp.setContentType("text/json");
        resp.setCharacterEncoding("UTF-8");
        OutputStream out = resp.getOutputStream();
        try {
            //System.out.println("格式化json:"+ JSON.toJSONString(obj));
            JSON.writeJSONString(out, obj, SerializerFeature.WriteDateUseDateFormat);
        } finally {
            out.flush();
            out.close();
        }
    }
}
