在maven项目中,我尝试使用maven资源过滤替换一些令牌,但它不起作用.我有一些其他项目可行,但在这个单项目中不起作用,不确定有什么问题.

属性文件位于/src/main/resources/my.properties中

我尝试了不同的maven命令如下,但不起作用.

mvn clean install
mvn clean install resources:resources

my.properties

### Spring boot properties
jdbc.url=${jdbc.url}
ldap.domain=${ldap_domain}
ldap.url=${ldap_url}

我正在使用AngularJS Dropdown Multiselect. http://dotansimha.github.io/angularjs-dropdown-multiselect/#/

我想要同时使用这两个事件.但不知道如何配置两者.我只能成功配置其中一个.

onItemSelect(property)

和

onItemDeselect(property)

HTML

<div ng-dropdown-multiselect="" options="property.dropdowns" selected-model="property.propertyValues"
                            extra-settings="multiSelectDropdownSettingsMaxOne" ng-required="property.startDate != null" events="onItemSelect(property)"></div>

更新

我用逗号分隔符尝试这样但是出错了

<div ng-dropdown-multiselect="" options="property.dropdowns" selected-model="property.propertyValues" extra-settings="multiSelectDropdownSettingsMaxOne" ng-required="property.startDate != null" events="onItemSelect(property), onItemDeSelect(property)"></div>

Spring Security基本示例给出了此异常.

错误:"通用匹配模式('/**')在过滤器链中的其他模式之前定义,导致它们被忽略.请检查命名空间或FilterChainProxy bean配置中的顺序"

我在同一个问题上查了很多帖子.但找不到任何解决方案.任何人都可以部署一个hello spring security吗？

我使用的是这些版本 - Spring 3.2.0.RELEASE/Spring security 3.2.0.RELEASE/Tomcat 7/Java 1.7.

我使用下面的JDBC代码来调用一个带有Array输入的Oracle存储过程.

但是以下三个类已被弃用.如何更换？

import oracle.sql.ArrayDescriptor;
import oracle.sql.STRUCT;
import oracle.sql.StructDescriptor;

Java代码

        Object[] reportArray = new Object[3]; 
        STRUCT[] struct = new STRUCT[reports.size()];

        ArrayDescriptor arrayDescriptor = new ArrayDescriptor(new SQLName("T_REPORT_TABLE", (OracleConnection) connection), connection);
        StructDescriptor structDescriptor = StructDescriptor.createDescriptor("R_REPORT_OBJECT", connection);

        int arrayIndex = 0;
        for (Report data : reports) {
            reportArray[0] = data.getXXX();
            reportArray[1] = data.getYYY();
            reportArray[2] = data.getZZZ();

            struct[arrayIndex++] = new STRUCT(structDescriptor, connection, reportArray);
        }

        oracle.sql.ARRAY reportsArray = new oracle.sql.ARRAY(arrayDescriptor, connection, struct);
        callableStatement.setArray("T_REPORT_IN", reportsArray);

        callableStatement.executeUpdate();

我只是在我的电脑上设置Grails，然后按照参考 http://grails.org/doc/latest/guide/gettingStarted.html#creatingAnApplication

在 ReactJS 中，在我的子组件中，输入 > 文本上的 onChange() 事件仅采用一个值，并且不会在每次按键时保留先前的值。

我正在尝试捕获子表单中的输入，并希望将其传输给父表单。实际上，我正在尝试重用子表单来创建和编辑页面。

我的完整代码和盒子在这里 https://codesandbox.io/embed/sleepy-stallman-fbyhh?fontsize=14

子组件

    import React, { Component } from "react";
    import { Form } from "react-bootstrap";

    export default class EmployeeForm extends Component {
      constructor(props) {
        super(props);
        console.log("this.props.employee ", this.props.employee);
      }

      /** Generic handle change events for all fields */
      handleChange = e => {
        this.props.employee[e.target.id] = e.target.value;
        console.log(e.target.value);
      };

      //   handleChange = (key, e) => {
      //     e.preventDefault();
      //     console.log(key);

我正在尝试在LDAP(Apache Directory Server)中创建一个新的Person条目.我可以创建一个没有国家objectClass的人,如下所示.

            dn[n]: uid=dduck,ou=people,dc=example,dc=com
            objectClass: top
            objectClass: person
            objectClass: organizationalPerson
            objectClass: inetOrgPerson
            uid: dduck
            sn: Duck
            cn: Donal Duck

但我也想为这个人添加一个国家.所以我添加了country objectClass,如下所示.

            dn[n]: uid=dduck,ou=people,dc=example,dc=com
            objectClass: country
            objectClass: top
            objectClass: person
            objectClass: organizationalPerson
            objectClass: inetOrgPerson
            uid: dduck
            sn: Duck
            c: FR
            cn: Donal Duck

但它失败了以下错误,有什么想法吗？

PrimeNG， p-table组件，当数据重新加载时，表重置为第一个分页器选项卡。

重新加载数据时，有什么方法可以阻止该行为并使分页器保留在同一选定选项卡中（例如 2 或 4 或 5 等）？

我每 10 秒重新加载一次数据，方法是在循环中使用 setTimeout() 调用 RestAPI，直到它停留在该页面上。

超文本标记语言

    <p-table #dt [columns]="cols" [value]="dataMarts" [paginator]="true" [rows]="15" [pageLinks]="5" [rowsPerPageOptions]="[5,10,15,20,50,100,200,500,1000]"sortField="Id" resetPageOnSort="false">

参考： https: //www.primefaces.org/primeng/#/table

不确定此行为是否与上述链接的“更改检测”部分中给出的解释有关。

更新：- 这个问题实际上是由属性sortField="Id"引起的，它导致始终显示第一个选项卡。去掉后效果很好。

在 ReactJS 中，我想动态启用/禁用按钮。为此，我创建了一个函数来检查状态中的表单字段。但这不起作用。

我尝试了下面的代码

render() {


    const canSave = true;  // Working

    // Not working
    const canSave = () => {
        const { paramCode, paramDesc, paramValue } = this.state.row;
        if (this.state.row && paramCode && paramDesc && paramValue) {
            return true;
        }
        return false
    }



    /* For Create Dialog  */
    let createDialogFooter = <div className="ui-dialog-buttonpane p-clearfix">
        <Button label="Save"  disabled={canSave} />
    </div>;

控制台错误：-

    index.js:1375 Warning: Invalid value for prop `disabled` on <button> tag. Either remove it from the element, or pass a …

从输入中，Stream<Map<String,Float>我试图找到具有最大值的独特分析物。我尝试了以下但没有得到预期的结果。我在收集价值时犯了一些错误。

样本输入数据： List<Map<String,Float>

{HNO3=2.005}
{HNO3=2.009}
{HCl=10.2}
{F-=0.0, HNO3=50.0}

Actual result   : {HCl=Optional[HCl=10.2], F-=Optional[F-=0.0], HNO3=Optional[HNO3=50.0]}
Expected result : {HCl=10.2, F-=0.0, HNO3=50.0}

我试过的Java代码：-

finalResponse.getChosenStartingMaterials()
    .stream()
    .map(Analyte::getMatrixUtilisationMap)  // Stream<Map<String,Float>>
    .flatMap(it -> it.entrySet().stream())   
    .collect(Collectors.groupingBy(Map.Entry::getKey, Collectors.maxBy((m1, m2) -> m1.getValue().compareTo(m2.getValue()))))
