Vaadin 7& Spring Boot:SqlContainer不能与Filter一起使用

标签: mysql spring vaadin vaadin4spring

Spring Boot:1.3.2.RELEASE 瓦丁:7.6.3 Mysql:mysql-java-connector-5.1.38 HikariCP:2.4.3

因此,我创建了一个仅包含 id 名称列的表格。然后是一个vaadin componant Table来显示表的内容。到现在为止一切都很好。然后我尝试用vaadin Filter过滤表,如果连接池是 com.vaadin.data.util.sqlcontainer.connection.SimpleJDBCConnectionPool ,它就可以工作,如果是 com则不行.vaadin.data.util.sqlcontainer.connection.J2EEConnectionPool 我使用HikariCP作为数据源。

DBConfig.java

@Configuration
@EnableTransactionManagement
public class DatabaseConfig {

@Bean
public HikariConfig hikariConfig() {
    HikariConfig config = new HikariConfig();
    config.setDriverClassName("com.mysql.jdbc.Driver");
    config.setJdbcUrl("jdbc:mysql://localhost:3306/test?autoReconnect=true&useSSL=false");
    config.setUsername("root");
    config.setPassword("root");
    config.setMaximumPoolSize(20);
    config.setPoolName("connectionPool");
    return config;
}

@Bean
public DataSource dataSource() {
    HikariDataSource dataSource = new HikariDataSource(hikariConfig());
    return dataSource;
}

ApplicationUI.java

@Autowired
private J2EEConnectionPool connectionPool;

@Override
protected void init(VaadinRequest arg0) {
    TableQuery tq = new TableQuery("medecine", connectionPool);// it does not work if I use HikariCP as the J2EEConnectionPool

JDBCConnectionPool pool = new SimpleJDBCConnectionPool("com.mysql.jdbc.Driver",
                "jdbc:mysql://localhost:3306/test?autoReconnect=true&useSSL=false", "root", "root");
TableQuery tq = new TableQuery("medecine", connectionPool);// it works if I use **SimpleJDBCConnectionPool**.

    container = new SQLContainer(tq);
    table = new Table();
    table.setContainerDataSource(container);
    table.setWidth(100, Unit.PERCENTAGE);
    mainLayout.addComponent(table);

Button addFilter = new Button("filter", new ClickListener() {

        private static final long serialVersionUID = -7071683058766115266L;

        @Override
        public void buttonClick(ClickEvent arg0) {
            Filter filter = new SimpleStringFilter("name", "medecine2", true, false);
            container.addContainerFilter(filter);
        }
    });
mainLayout.addComponent(addFilter);
}

我选择HikariCP作为数据源的原因是为了获得更好的性能,而且我不确定vaadin连接池是否会比HikariCP更好。或者,它仅限于过滤功能的vaadin连接池?
