不知道是人品问题还是什么,我使用springBoot整合Mybatis模块后,竟然起作用
下面是我的解决办法:
springBoot :1.5.10.RELEASE
idea : 2017.4
mysql :5.5
Druid数据源
步骤:
1.创建springBoot工程,导入web ,Mysql ,jdbc ,Mybatis模块
2.在pom中导入 druid,Mybatis,Mybatis-spring

4. 在application.yml中配置数据源
spring:
datasource:
username: root
password: 123456
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:3306/ssm
type: com.alibaba.druid.pool.DruidDataSource
# 数据源其他配置
initialSize: 5
minIdle: 5
maxActive: 20
maxWait: 60000
timeBetweenEvictionRunsMillis: 60000
minEvictableIdleTimeMillis: 300000
validationQuery: SELECT 1 FROM DUAL
testWhileIdle: true
testOnBorrow: false
testOnReturn: false
poolPreparedStatements: true
# 配置监控统计拦截的filters,去掉后监控界面sql无法统计,'wall'用于防火墙
filters: stat,wall,log4j
maxPoolPreparedStatementPerConnectionSize: 20
useGlobalDataSourceStat: true
connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
5. 创建Druid配置类
@Configuration
public class DruidConfig {
@Bean
@ConfigurationProperties(prefix = "spring.datasource")
public DruidDataSource druidDataSource(){
return new DruidDataSource();
}
@Bean
public ServletRegistrationBean servletRegistrationBean(){
ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
Map<String,String> map = new HashMap<>();
map.put("loginUsername", "admin");
map.put("loginPassword", "123456");
map.put("allow", "localhost");
servletRegistrationBean.setInitParameters(map);
return servletRegistrationBean;
}
@Bean
public FilterRegistrationBean filterRegistrationBean(){
FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
Map<String,String> inintParam = new HashMap<>();
//不过滤静态资源和后台请求
inintParam.put("exclusions","*.js,*.css,/druid/*");
filterRegistrationBean.setInitParameters(inintParam);
return filterRegistrationBean;
}
}
6.使用Mybatis自动生成器生成代码
7.创建Mybatis配置类:(一定配置成两个配置类,否则会报错)
MybatisConfig:(mybatis主配置类)
@Configuration
@EnableTransactionManagement
public class MyBatisConfig implements TransactionManagementConfigurer {
@Autowired
DataSource dataSource;
@Bean(name = "sqlSessionFactory")
public SqlSessionFactory sqlSessionFactoryBean() {
SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
bean.setDataSource(dataSource);
bean.setTypeAliasesPackage("com.ssm.pojo");
//分页插件
PageHelper pageHelper = new PageHelper();
Properties properties = new Properties();
properties.setProperty("reasonable", "true");
properties.setProperty("supportMethodsArguments", "true");
properties.setProperty("returnPageInfo", "check");
properties.setProperty("params", "count=countSql");
pageHelper.setProperties(properties);
//添加插件
bean.setPlugins(new Interceptor[]{pageHelper});
//添加XML目录
ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
try {
bean.setMapperLocations(resolver.getResources("classpath:mapper/*.xml"));
return bean.getObject();
} catch (Exception e) {
e.printStackTrace();
throw new RuntimeException(e);
}
}
@Bean
public SqlSessionTemplate sqlSessionTemplate(SqlSessionFactory sqlSessionFactory) {
return new SqlSessionTemplate(sqlSessionFactory);
}
@Bean
@Override
public PlatformTransactionManager annotationDrivenTransactionManager() {
return new DataSourceTransactionManager(dataSource);
}
}
MyBatisMapperScannerConfig:(扫描mapper dao)
@Configuration
@AutoConfigureAfter(MyBatisConfig.class)//必须加这个注解,否则会报错
public class MyBatisMapperScannerConfig {
@Bean
public MapperScannerConfigurer mapperScannerConfigurer() {
MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();
mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory");
mapperScannerConfigurer.setBasePackage("com.ssm.dao");
return mapperScannerConfigurer;
}
}
8.创建controller测试是否可用
