这篇文章主要介绍了spring cloud 配置阿里数据库连接池 druid,本文通过实例代码给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下

1.配置pom

				?

									<!-- druid 数据库连接池  -->

									       <dependency>

									           <groupId>com.alibaba</groupId>

									           <artifactId>druid</artifactId>

									           <version>1.1.12</version>

									           <exclusions>  

									               <exclusion>  

									                   <groupId>com.alibaba</groupId>  

									                   <artifactId>jconsole</artifactId>  

									               </exclusion>  

									               <exclusion>  

									                   <groupId>com.alibaba</groupId>  

									                   <artifactId>tools</artifactId>  

									               </exclusion>  

									           </exclusions>

									       </dependency>

2.配置application.properties

				?

									#druid连接池

									spring.datasource.type: com.alibaba.druid.pool.DruidDataSource

									#最大活跃数

									spring.datasource.maxActive: 20

									#初始化数量

									spring.datasource.initialSize: 1

									#最大连接等待超时时间

									spring.datasource.maxWait: 60000

									#打开PSCache，并且指定每个连接PSCache的大小

									spring.datasource.poolPreparedStatements: true

									spring.datasource.maxPoolPreparedStatementPerConnectionSize: 20

									#通过connectionProperties属性来打开mergeSql功能；慢SQL记录

									#connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000

									spring.datasource.minIdle: 1

									spring.datasource.timeBetweenEvictionRunsMillis: 60000

									spring.datasource.minEvictableIdleTimeMillis: 300000

									spring.datasource.validationQuery: select 1 from dual

									spring.datasource.testWhileIdle: true

									spring.datasource.testOnBorrow: false

									spring.datasource.testOnReturn: false

									#配置监控统计拦截的filters，去掉后监控界面sql将无法统计,'wall'用于防火墙

									filters: stat, wall, log4j

3.Config配置类

				?

									/**

									 * 说明：第一数据源配置

									 * 作者：FH

									 * from：fhadmin.cn

									 */

									@Configuration

									@MapperScan(basePackages = MasterDataSourceConfig.PACKAGE, sqlSessionFactoryRef = "masterSqlSessionFactory") //扫描 Mapper 接口并容器管理

									public class MasterDataSourceConfig {

									    static final String PACKAGE = "org.fh.mapper.dsno1";                                //master 目录

									    static final String MAPPER_LOCATION = "classpath:mybatis/dsno1/*/*.xml";            //扫描的 xml 目录

									    static final String CONFIG_LOCATION = "classpath:mybatis/dsno1/mybatis-config.xml"; //自定义的mybatis config 文件位置

									    static final String TYPE_ALIASES_PACKAGE = "org.fh.entity";                         //扫描的 实体类 目录

									    @Value("${datasource.no1.url}")

									    private String url;

									    @Value("${datasource.no1.username}")

									    private String user;

									    @Value("${datasource.no1.password}")

									    private String password;

									    @Value("${datasource.no1.driver-class-name}")

									    private String driverClass;

									    @Bean(name = "masterDataSource")

									    @Primary

									    public DataSource masterDataSource() {

									        DruidDataSource dataSource = new DruidDataSource();

									        dataSource.setDriverClassName(driverClass);

									        dataSource.setUrl(url);

									        dataSource.setUsername(user);

									        dataSource.setPassword(password);

									        return dataSource;

									    }

									    @Bean(name = "masterTransactionManager")

									    public DataSourceTransactionManager masterTransactionManager() {

									        return new DataSourceTransactionManager(masterDataSource());

									    @Bean(name = "masterSqlSessionFactory")

									    public SqlSessionFactory masterSqlSessionFactory(@Qualifier("masterDataSource") DataSource masterDataSource)throws Exception {

									        final SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();

									        sessionFactory.setDataSource(masterDataSource);

									        sessionFactory.setMapperLocations(new PathMatchingResourcePatternResolver().getResources(MasterDataSourceConfig.MAPPER_LOCATION));

									        sessionFactory.setConfigLocation(new DefaultResourceLoader().getResource(MasterDataSourceConfig.CONFIG_LOCATION));

									        sessionFactory.setTypeAliasesPackage(MasterDataSourceConfig.TYPE_ALIASES_PACKAGE);

									        return sessionFactory.getObject();

									}

-----------------------------------------------------------------自定义表单
28. 定义模版：拖拽左侧表单元素到右侧区域，编辑表单元素，保存表单模版
29. 表单模版：编辑维护表单模版，复制表单模版，修改模版类型，预览表单模版
30. 我的表单：选择表单模版，编辑表单规则，是否上传图片、附件、开启富文本、挂靠流程开关等
31. 表单数据：从我的表单进去可增删改查表单数据，修改表单规则
32. 挂靠记录：记录表单数据和流程实例ID关联记录，可删除
