如何在Springs MVC 4中使用HikariCP和JdbcTemplate

我是Springs MVC的新手，我尝试将HikariCP与JdbcTemplate集成。但是得到了很多错误的帮助，比如如何将JdbcTemplate指向HikariCP数据源

在applicationContext.xml中

<bean id="dataSource" class="com.zaxxer.hikari.HikariConfig">
<property name="poolName" value="springHikariCP" />
<property name="connectionTestQuery" value="SELECT 1" />
<property name="dataSourceClassName"       value="com.mysql.jdbc.jdbc2.optional.MysqlDataSource" />
<property name="dataSourceProperties">
    <props>
        <prop key="url">${jdbc.url}</prop>
        <prop key="user">${jdbc.username}</prop>
        <prop key="password">${jdbc.password}</prop>
    </props>
</property>
</bean>

 <bean id="jdbcTemplate" class="com.zaxxer.hikari.HikariDataSource" destroy- method="close">
     <property name="dataSource" ref="dataSource"></property>
 </bean>

---

我使用SpringJavaConfig配置数据源并获取jdbctemplate。我认为这是最好的

@Bean
    public DataSource getDataSource() {

        private HikariDataSource dataSource() {
           final HikariDataSource ds = new HikariDataSource();
           ds.setMaximumPoolSize(100);
           ds.setDriverClassName("oracle.jdbc.driver.OracleDriver"); 
           ds.setJdbcUrl("jdbc:oracle:thin:@localhost:1521:XE"); ;
           ds.setUsername("username");
           ds.setPassword("password");
           return ds;
        }

    }

    @Bean
    public JdbcTemplate getJdbcTemplate() {

        return new JdbcTemplate(getDataSource());
    }

我希望这对你有用

        private HikariDataSource dataSource() {
           final HikariDataSource ds = new HikariDataSource();
           ds.setMaximumPoolSize(100);
           ds.setDriverClassName("oracle.jdbc.driver.OracleDriver"); 
           ds.setJdbcUrl("jdbc:oracle:thin:@localhost:1521:XE"); ;
           ds.setUsername("username");
           ds.setPassword("password");
           return ds;
        }

    }

    @Bean
    public JdbcTemplate getJdbcTemplate() {

        return new JdbcTemplate(getDataSource());
    }
