The key step SSM framework based on the full build Detailed notes

1. Download SSM framework required jar package

2. Create a data table, the use of reverse engineering according Mybatis table generating entity classes (pojo), SQL mapping file (mapper.xml) and dynamic proxy interfaces (mapper.java)

   (1) preparing a data table

   (2) Create a Java project (name Custom)

   (3) Download mybatis-generator-core-1.3.2-bundle.zip, unzip the file, the MyBatis-Generator-Core-1.3.2.jar , ojdbc.jar and Mybatis depend mybatis-3.3.1.jar added the project build directory (build path)

        docs file index.html relevant knowledge generated automatically

   (4) create and write configuration files in src

        generator.xml

       <?xml version="1.0" encoding="UTF-8"?>

</generatorConfiguration>

 The following Java code execution

public class aa{
    public static void main(String []args){
        File f=new File("src/generator.xml");
        List<String>  warnings=new ArraytList<String>();
        ConfigurationParser cp=new  ConfigurationParser(warnings);
        Configuration config=cp.parseConfiguration(f);
        DefaultShellCallBack callBack=new DefaultShellCallBack(true);
        MyBatisGenerator generator=new MyBatisGenerator(config,callBack,warnings);
        generator.generate(null);
        
    }
    
}

3. Configure Notes

 

@Component
public class ElectricOrder{
     //属性
     ...属性的set和get体方法
}
@Repository
public class ElectricOrderDao {
     @Autowired(required =false) ElectricOrderMapper electricOrderMapper;
    
}
@Service

public class ElectricOrderService {
     @Autowired(required =false) ElectricOrderDao electricOrderDao;
    
}


@Controller

public class ElectricOrderService {
  @Autowired
        private  ElectricOrderService electricOrderService;

 

 spring configure the scanner

   

<! - automatic scanning, support the use of annotation mode, automatic assembly the bean -> 
 
<context: component- Scan Base - Package = "com.zy.mapper" />

<context:component-scan base-package="com.zy.dao" />

<context:component-scan base-package="com.zy.service" />

<context:component-scan base-package="com.zy.pojo" />
