SSM框架整合
基础整合

创建.properties文件用于存放数据库相关数据。
# 驱动配置，可根据url自动识别，可有可无
druid.driverClassName=com.mysql.cj.jdbc.Driver
# 连接数据库url
druid.url=jdbc:mysql://localhost:3306/${数据库名称}?autoReconnect=true&useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false
# 用户名
druid.username=${username}
# 密码
druid.password=${password}
# 初始化连接数量
druid.initialSize=5
# 最大连接数量
druid.maxActive=10
# 最长等待时间
druid.maxWait=3000
创建druid配置类
public class DruidConfig {
@Value("${druid.driverClassName}")
private String driverClassName;
@Value("${druid.url}")
private String url;
@Value("${druid.username}")
private String username;
@Value("${druid.password}")
private String password;
@Value("${druid.initialSize}")
private int initSize;
@Value("${druid.maxActive}")
private int maxActive;
@Value("${druid.maxWait}")
private int maxWait;
/**
* 创建数据库连接池对象
* @return 数据库连接池对象
*/
@Bean
public DataSource dataSource() {
DruidDataSource ds = new DruidDataSource();
ds.setDriverClassName(driverClassName);
ds.setUrl(url);
ds.setUsername(username);
ds.setPassword(password);
ds.setInitialSize(initSize);
ds.setMaxActive(maxActive);
ds.setMaxWait(maxWait);
return ds;
}
/**
* 创建数据库连接池事务管理器
* @return 数据库连接池事务管理器对象
*/
@Bean
public PlatformTransactionManager transactionManager(DataSource dataSource) {
DataSourceTransactionManager transactionManager = new DataSourceTransactionManager();
transactionManager.setDataSource(dataSource);
return transactionManager;
}
}
创建MyBatis配置类
public class MyBatisConfig {
/**
* 创建MyBatis的工厂类对象
* @param dataSource
* @return SqlSessionFactoryBean
*/
@Bean
public SqlSessionFactoryBean sqlSessionFactory(DataSource dataSource) {
SqlSessionFactoryBean ssfb = new SqlSessionFactoryBean();
ssfb.setDataSource(dataSource);
ssfb.setTypeAliasesPackage("org.YD");
return ssfb;
}
/**
* 创建Mapper代理扫描器对象
* 将mapper接口文件都自动注入到IoC容器中，
* 实现类Bean的名称默认为接口类名的首字母小写
* @return MapperScannerConfigurer
*/
@Bean
public MapperScannerConfigurer mapperScannerConfigurer() {
MapperScannerConfigurer msc = new MapperScannerConfigurer();
msc.setBasePackage("org.YD.dao");
return msc;
}
}
创建Spring核心框架配置类
@Configuration
@ComponentScan({"org.YD.service"})
@PropertySource({"classpath:druid.properties"})
@EnableTransactionManagement
@Import({DruidConfig.class, MyBatisConfig.class})
public class SpringConfig {
}
创建SpringMvc配置类
@Configuration
@EnableWebMvc
@ComponentScan("org.YD.controller")
public class SpringMvcConfig {
}
创建Tomcat初始化类
public class ServletConfig extends AbstractAnnotationConfigDispatcherServletInitializer {
/**
* 配置Spring核心容器
* @return Spring核心容器配置类数组
*/
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[]{SpringConfig.class};
}
/**
* 配置SpringMVC容器
* @return SpringMVC容器配置类数组
*/
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[]{SpringMvcConfig.class};
}
/**
* 配置哪些请求由SpringMVC接管
* @return 接管路径的字符串数组
*/
@Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
/**
* 配置过滤器
* @return 过滤器数组
*/
@Override
protected Filter[] getServletFilters() {
CharacterEncodingFilter filter = new CharacterEncodingFilter();
filter.setEncoding("utf-8");
return new Filter[]{filter};
}
}
如上就能完成SSM框架的基础整合了。
