package com.ithm.config;

import com.alibaba.druid.pool.DruidDataSource;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;

import javax.sql.DataSource;

public class jdbcConfig {
    @Value("${jdbc.driver}")
    private String driver;
    @Value("${jdbc.url}")
    private String url;
    @Value("${jdbc.username}")
    private  String username;
    @Value("${jdbc.password}")
    private String password;

   @Bean
    public DataSource dataSource(){
        DruidDataSource dataSource = new DruidDataSource();
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://localhost:3306/xsytest");
        dataSource.setUsername(username);
        dataSource.setPassword(password);
        return dataSource;
    }
}

jdbcConfig数据源

第一步配置数据库

第二步 这步配置mybates数据要扫的包和数据类型印射，详细代码可复制于代码

mybatiesConfig

第三步  servlet配置请求解析器

package com.ithm.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class ServletConfig extends AbstractAnnotationConfigDispatcherServletInitializer {
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[]{SpingConfig.class};
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[]{SpringmvcConfig.class};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
}

package com.ithm.config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.context.annotation.PropertySource;

@Configuration
@ComponentScan("com.ithm.service")
@PropertySource("classpath:Jdbc.properties")
@Import({jdbcConfig.class,MybatiesConfig.class})
public class SpingConfig {
}

package com.ithm.config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@Configuration
@ComponentScan("com.ithm.controller")
@EnableWebMvc
public class SpringmvcConfig {

}

最后差一人propetie配置文件

jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/xsytest
jdbc.username = root
jdbc.password = 142857

++++++++++++++++++++++++++++++++++++++++++++++++++++++最后编写测试类和postman工具测试+++++++++++++++++++++++++++

package com.ithm.text;

import com.ithm.config.SpingConfig;
import com.ithm.domain.Book;
import com.ithm.service.BookService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SpingConfig.class)
public class servie {
 @Autowired
private BookService bookService;
@Test
public void testgetbyid(){
    Book book = bookService.getByid(1);
    System.out.println("ok");
    System.out.println(book);

}
}

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++以上是junit测试++++++++++++++++++++++++++

如果是postMan接口测试需要：

如果是sava接口需要{“a”:"b","ee":"bb"}  pust传这样格式数据上去  选择jsons格式

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++=

开启事务：

需要在springConfig

1  新增注解  @EnableTransactionManagement

2 在jdbcConfig 中新增代码，事务管理器

@Bean
public PlatformTransactionManager platformTransactionManager(DataSource dataSource){
    DataSourceTransactionManager ds = new DataSourceTransactionManager();
    ds.setDataSource(dataSource);
    return ds;
}

3，最后在servlet接口层上加事务  @Transactional
