Gis WFS事务插入请求上的零星java.lang.IllegalArgumentException

我在PostGIS上的Tomcat容器中运行GeoServer，并使用OpenLayers 3 WFS事务（AJAX POST中的xml）将单个点（一次）插入数据库。工作区是mypoints，商店是my_points。下面是Javascript：

// MY_POINT LAYER
var mypointssource = new ol.source.Vector({
    url: 'http://localhost:8080/geoserver/mypoints/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=mypoints:my_points&srsname=EPSG:4326&outputFormat=application/json',
    format: new ol.format.GeoJSON()
});

var mypoints = new ol.layer.Vector({
    source: mypointssource,
    style: new ol.style.Style({
        image: new ol.style.Circle({
            radius: 8,
            fill: new ol.style.Fill({color: 'yellow'})
        })
    })
});

// DRAW_PNT LAYER
var drawpntsource = new ol.source.Vector();

var drawpnt = new ol.layer.Vector({
    source: drawpntsource,
    style: new ol.style.Style({
        image: new ol.style.Circle({
            radius: 3,
            fill: new ol.style.Fill({
                color: 'red'
            })
        })
    })
});

// MAPQUEST TILE LAYER
var tile = new ol.layer.Tile({
    source: new ol.source.MapQuest({layer: 'sat'})
});

// THE VIEW
var pointview = new ol.View({
    center: [0, 0],
    zoom: 3,
    maxZoom: 16
});

// THE MAP
var map = new ol.Map({
    target: 'map',
    layers: [tile, mypoints, drawpnt],
    view: pointview
});

// REFOCUS VIEW ON MYPOINTS +/- SOME PADDING
mypointssource.on('change', function(e) {
    if (mypointssource.getState() == 'ready') {
        var paddedExtent = [];

        ext = mypointssource.getExtent();
        var dX = 0.08 * (ext[2] - ext[0]);
        var dY = 0.08 * (ext[3] - ext[1]);

        paddedExtent.push(ext[0] - dX);
        paddedExtent.push(ext[1] - dY);
        paddedExtent.push(ext[2] + dX);
        paddedExtent.push(ext[3] + dY);

        pointview.fit(paddedExtent, map.getSize());
    }
});

// DRAW INTERACTION
var entry = {};
var drawbutton = $('#draw');
var drawinteraction = new ol.interaction.Draw({
    source: drawpntsource,
    type: 'Point'
});

// DRAW TOGGLE BUTTON:
var active = false;
function toggleDraw() {
    if (active == false) {
        map.addInteraction(drawinteraction);
        active = true;
    } else {
        map.removeInteraction(drawinteraction);
        active = false;
    }
}
// ADD EVENT HANDLER TO BUTTON
drawbutton.on('click', toggleDraw);

// WFS TRANSACTION FORMAT OBJ
var wfst = new ol.format.WFS({
    featureNS: 'mypoints',
    featureType: 'my_points',
    schemaLocation: "http://schemas.opengis.net/wfs/1.0.0/wfs.xsd \
        http://schemas.opengis.net/wfs/1.0.0/WFS-transaction.xsd \
        http://localhost:8080/geoserver/mypoints/wfs/DescribeFeatureType?" + 
        "typename=mypoints:my_points"
});

// ON DRAW END
drawinteraction.on('drawend', function(evt) {
    map.removeInteraction(drawinteraction);
    drawbutton.hide();
    var newpoint = evt.feature;
    newpoint.set('the_geom', newpoint.getGeometry());
    newpoint.set('geometry', null);
    newpoint.set('title', "A generic title");
    var node = wfst.writeTransaction([newpoint], null, null, {
        gmlOptions: {srsName: "EPSG:3857"},
        featureNS: "mypoints",
        featureType: "my_points"
    });

    $('#messagebox').text(new XMLSerializer().serializeToString(node));

    // THE WFS AJAX TRANSACTION REQUEST:
    $.ajax({
        type: "POST",
        url: "http://localhost:8080/geoserver/mypoints/wfs",
        data: new XMLSerializer().serializeToString(node),
        contentType: 'text/xml',
        success: function(data) {
            var result = wfst.readTransactionResponse(data);
            $('#messagebox').text(data);
            console.log(data);
        },
        error: function(e) {
            var errorMsg = e ? (e.status + ' ' + e.statusText) : "";
            $('#messagebox').text(errorMsg);
        },
        context: this
    });
});

这在大约80%的时间内有效，偶尔与我3天多以来无法识别的内容有关，它会导致此服务器错误：

我是GeoServer的新手，我认为问题在于我形成请求的方式。要么是URL，要么是与XML模式有关的内容，但就我个人而言，我无法理解它是如何工作的，或者为什么它有时工作，而不是其他工作

注意：顶部未指定为名称空间/位置对的架构位置警告即使在成功的事务中也会出现，我认为这不是直接原因，尽管如果有人知道这是怎么回事，那是另一个问题

谢谢

发现这个答案很有帮助。换言之：基本上，当GeoServer获取schemaLocation中列出的XML模式定义时，如果.xsd文件驻留在同一台服务器上（例如，它可以作为DescribeFeatureType请求访问，就像我在ol.format.WFS选项中所做的那样），它首先根据已知主机列表检查url的主机名但是，由于一个据称的错误，当它被引用为“localhost”时，它无法识别自己，并且认为它是其他人，它向自己发送了一个获取文件的请求。然后生成一个线程来处理这个GET请求，它与初始线程竞争对模式文件的访问。因此，偶尔会出现僵局

我已通过从事务XML的schemaLocation属性中删除DescribeFeatureType url修复了此问题
