我使用与Mysql集成的配置数据库用于报告目的.我浏览了文档,但无法找到任何解释如何在基于SQL的问题中实现过滤器的示例.

我发现的唯一例子是关于日期范围和字段过滤器,而不是文本和数字.

任何人都可以提供有关如何使用文本过滤器的文档或任何示例.

我正在使用元数据库版本v0.24.2

我试图运行的查询就是这个

 SELECT  @a:=@a+1 "Serial Number", ssk_transaction.transactionId AS "TranId",   
t2.typeName AS "Transaction Type",  
ssk_transaction.createdTime AS "GenDate", t3.deviceName AS "Machine Name",  
 t3.deviceLocation AS "Machine Location", t9.eventApiName AS 'API Name' ,  
t8.vendorResultCode AS 'Last API Response',  
(SELECT createdTime FROM ssk_transaction_event_detail t4 WHERE t4.transactionId  
 = ssk_transaction.transactionId ORDER BY id DESC LIMIT 1) AS "Last API Called",  
(SELECT IFNULL(SUM(t5.itemName * t4.itemCount), 0) FROM  
 ssk_transaction_cash_detail t4  
LEFT JOIN ssk_inventory_item t5 ON (t4.itemId = t5.itemId)  
LEFT JOIN ssk_inventory_category t10 ON (t5.categoryId = t10.categoryId) …

我正在处理一个需求。我需要做的是从数据库中检索最后输入的日期，增加它，然后检查这一天是否是星期六。我陷入困境的部分是如何检查第二天是否是星期六我正在使用 primefaces 3.5 jsf2.1 apache tomcat 7.0.39

FacesContext context = FacesContext.getCurrentInstance();
    Map requestMap = context.getExternalContext().getRequestParameterMap();
    String value = (String) requestMap.get("id");
    Integer id = Integer.parseInt(value);
    SimpleDateFormat sdf= new SimpleDateFormat();
    String sector=new String();
    setFund(new Fund());
    for(Map row:fund_grid){
        Integer edit_id=(Integer.parseInt((String) row.get("fund_id")));
        if(id.equals(edit_id)){
            sector=(String) row.get("fund_sector_label");
            mfp.setFund_id(Integer.parseInt( (String) row.get("fund_id")));
            fund.setFund_id( (String) row.get("fund_id"));
            setValidity_date(request_invoker.select_validity_date());
            try {
                Date ndate=sdf.parse((String) getValidity_date().get(0).get("validitydate"));

// 这里的日期是从数据库值 15-11-2013 中退休的

//现在增加一天

                Calendar c = Calendar.getInstance();
                c.setTime(ndate);
                c.add(Calendar.DATE, 1);
                fund.setNav_entry_date(c.getTime());

//这就是我被困的地方，我不知道如何检查日期是否是星期六

            if(fund.getNav_entry_date().equals(Calendar.SATURDAY))
                {
                c.add(Calendar.DATE, 2);
                fund.setNav_entry_date(c.getTime());
                }
                else
                {

我第一次使用 javamail，遇到了一些我不明白的异常，我在这里也看到了其他问题中的一些错误，但它们的答案对我没有帮助。这是我的代码。

        final String username = "imsan1@cdcpk.com";
        final String password = "**********";
        Properties props = System.getProperties();
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.host", "10.1.136.26");
        props.put("mail.smtp.port", "25");
        props.put( "mail.smtp.user" , username );
        props.put( "mail.smtp.password" , password );

        Session session = Session.getInstance(props,
          new SmtpAuthenticator(username, password)
          );


        try {

            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress("imsan1@cdcpk.com"));
            message.setRecipients(Message.RecipientType.TO,
                InternetAddress.parse("immni1@cdcpk.com"));
            message.setSubject("Testing Subject");
            message.setText("Dear Mail Crawler,"

正如问题标题中提到的，我面临问题Cannot determine embedded database driver class for database type NONE。我构建的应用程序是在 spring boot 上构建的，当我在 intellij 中运行代码时工作正常。

我关注了有关同一异常的几个问题，他们建议我需要spring.datasource在 application.properties 文件中添加属性。我已经有了它们，但仍然面临同样的问题。当我使用 intellij 的工件创建 jar 文件，然后通过以下命令运行它时，会出现此问题。 java - jar myJar.jar

我的 application.properties 文件

# ===============================
# = DATA SOURCE
# ===============================
spring.datasource.url = jdbc:mysql://localhost:3306/db_wssmith?useSSL=false
spring.datasource.username = 
spring.datasource.password = 
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

运行jar时出现错误日志

我有一个用以下sql在mysql上创建的表

CREATE TABLE `ssk_cms_category_transaction_type_relation` (
  `categoryId` int(11) NOT NULL,
  `typeId` int(11) NOT NULL,
  `createdTime` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`categoryId`,`typeId`),
  KEY `FK_ssk_cms_category_transaction_type_relation1` (`typeId`),
  CONSTRAINT `FK_ssk_cms_category_transaction_type_relation` FOREIGN KEY (`categoryId`) REFERENCES `ssk_cms_content_category` (`contentCategoryId`) ON DELETE CASCADE ON UPDATE CASCADE,
  CONSTRAINT `FK_ssk_cms_category_transaction_type_relation1` FOREIGN KEY (`typeId`) REFERENCES `ssk_transaction_type` (`typeId`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=latin1

在尝试使用intellij中的休眠持久性工具生成其模型时，如果我检查显示默认关系，则会收到以下错误，任何人都可以帮助我理解这一点。我尝试使用Google搜索，但未找到解决方案

我正在使用 Ubuntu 18.04 并在最新版本的 Intellij 中遇到以下异常 FATAL:gpu_data_manager_impl_private.cc(439)] GPU process isn't usable. Goodbye.错误中。尽管新的 helloworld 项目对我来说很好用，但当我打开任何远程存储库时，这在 Ultimate 和 Community 版本上都会发生。我可以成功克隆 repo，但 intellij 因此异常而崩溃

我也试过用 intellij 运行，--disable-gpu但对我不起作用。

我需要对实体进行分页和排序。

@Entity
@Table(name = "CATEGORY", catalog = "")
public class CategoryEntity {
 private CategoryEntity categoryByParentCategoryId;
 private Set<CategoryEntity> categoriesByCategoryId;


@ManyToOne(fetch = FetchType.LAZY,optional = false, cascade = CascadeType.PERSIST)
@JoinColumn(name = "PARENT_CATEGORY_ID", referencedColumnName = "CATEGORY_ID")
public CategoryEntity getCategoryByParentCategoryId() {
    return categoryByParentCategoryId;
}

public void setCategoryByParentCategoryId(CategoryEntity categoryByParentCategoryId) {
    this.categoryByParentCategoryId = categoryByParentCategoryId;
}

@OneToMany(mappedBy = "categoryByParentCategoryId", cascade = CascadeType.PERSIST)
public Set<CategoryEntity> getCategoriesByCategoryId() {
    return categoriesByCategoryId;
}

public void setCategoriesByCategoryId(Set<CategoryEntity> categoriesByCategoryId) {
    this.categoriesByCategoryId = categoriesByCategoryId;
}
