JasperListener?从Tomcat 8升级到Tomcat 9

由于Tomcat 8.0寿命已尽,我想直接将应用程序升级到Tomcat 9。

当我将基于Java的App从本地部署到服务器时,我有一个脚本覆盖了server.xml。我将服务器升级到tomcat 9,并尝试将应用程序放入其中,但是尝试启动它时出现错误。

    var pie = d3.pie()
      .sort(null)
      .value(d => this.width);

    var arc = d3Shape.arc()
      .innerRadius(this.innerRadius)
      .outerRadius(function (d) {
        return (this.radius - this.innerRadius) * (88 / 100.0) + this.innerRadius;
      });

    var outlineArc = d3Shape.arc()
      .innerRadius(this.innerRadius)
      .outerRadius(this.radius);

 var svg = d3.select("#id1").append("svg")
      .attr("width", this.width)
      .attr("height", this.height)
      .attr('viewBox', '0 0 ' + Math.min(this.width, this.height) + ' ' + Math.min(this.width, this.height))
      .data(data)
      .enter()
      .append("g")
      .attr("transform", "translate(" + Math.min(this.width, this.height) / 2 + "," + Math.min(this.width, this.height) / 2 + ")");

 d3.json(data, function (data) {
        data.forEach(function (d) {
          d.id = d.id;
          d.order = parseFloat(d.order);
          d.color = d.color;
          d.weight = parseFloat(d.weight);
          d.score = parseFloat(d.score);
          d.width = parseFloat(d.weight);
          d.label = d.label;
        });


    var path = svg.selectAll(".solidArc")
      .data(pie(data))
      .enter().append("path")
      .attr("fill", function(d) { return data.color ; })
      .attr("class", "solidArc")
      .attr("stroke", "black")
      .attr("d", <any>arc);

    var outerPath = svg.selectAll(".outlineArc")
      .data(pie(data))
      .enter().append("path")
      .attr("fill", "none")
      .attr("stroke", "black")
      .attr("class", "outlineArc")
      .attr("d", <any>outlineArc);

    var score =
    data.reduce(function (a, b) {
        //console.log('a:' + a + ', b.score: ' + b.score + ', b.weight: ' + b.weight);
        return a + (b.score * b.weight);
      }, 0) /
      data.reduce(function (a, b) {
        return a + b.weight;
      }, 0);

    svg.append("svg:text")
      .attr("class", "aster-score")
      .attr("dy", ".35em")
      .attr("text-anchor", "middle") // text-align: right
      .text(Math.round(score))
    });
   }
}

Tomcat 9不知道JasperListener。我搜索了此问题,并从apache找到了“ Jasper How to”页面,但我不明白。现在是否已安装Jasper,而无需在server.xml中插入JasperListener?从Tomcat 8升级到9时,我还需要更新其他内容吗?

org.apache.catalina.core.JasperListener不再需要。因此,如果您的server.xml中存在该文件-请注释掉它!
