基于spring5的ssm整合练习 -- day01 纯注解配置

一、搭建项目环境

1、创建父子工程

2、父工程中导入jar包

3、加入各个工程之间的依赖关系

parent --> domain --> dao --> service --> web

4、导入通用页面

5、创建Oracle数据库中的用户

创建用户：

分配角色：

二、加入配置类

1、dao层配置类

JdbcConfig.java

package com.ssm.config;

import javax.sql.DataSource;

import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.test.context.ContextConfiguration;

import com.mchange.v2.c3p0.ComboPooledDataSource;

/**
 * spring配置类
 * 
 * @author wingz
 *
 */

@ContextConfiguration // 将该java文件当作一个配置类
@MapperScan("com.ssm.dao") // 配置要扫描的Mybatis的注解的包
public class JdbcConfig {

	private String driverClass = "oracle.jdbc.driver.OracleDriver";

	private String jdbcUrl = "jdbc:oracle:thin:@192.168.88.6:1521:orcl";

	private String user = "ssm";

	private String password = "ssm";

	/**
	 * 创建数据源
	 * 
	 * @return
	 */
	@Bean // 该注解将返回的对象放入spring容器中
	public DataSource getDateSource() {
		ComboPooledDataSource dataSource = new ComboPooledDataSource();
		try {
			dataSource.setDriverClass(driverClass);
			dataSource.setJdbcUrl(jdbcUrl);
			dataSource.setUser(user);
			dataSource.setPassword(password);
		} catch (Exception e) {
			e.printStackTrace();
		}
		return dataSource;
	}

	/**
	 * 创建sessionFactory
	 * 
	 * @param dataSource
	 * @return
	 */
	@Bean
	public SqlSessionFactoryBean getSqlSessionFactoryBean(DataSource dataSource) {
		SqlSessionFactoryBean factory = new SqlSessionFactoryBean();
		factory.setDataSource(dataSource);
		return factory;
	}

}

2、service层配置类

TxConfig.java

package com.ssm.config;

import javax.sql.DataSource;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@ContextConfiguration // 将该java文件当作一个配置类
@ComponentScan("com.ssm.service") // 配置要扫描的service层的注解
@EnableTransactionManagement // 开始事务管理器的注解
public class TxConfig {

	/**
	 * 配置事务管理器
	 * 
	 * @param dataSource
	 * @return
	 */
	@Bean
	public DataSourceTransactionManager getDataSourceTransactionManager(DataSource dataSource) {
		DataSourceTransactionManager manager = new DataSourceTransactionManager();
		manager.setDataSource(dataSource);
		return manager;
	}
}

3、web层配置类

SpringMvcConfig.java

package com.ssm.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@ContextConfiguration // 将该java文件当作一个配置类
@ComponentScan("com.ssm.controller") // 配置要扫描的springmvc的注解的包
@EnableWebMvc // 相当于xml中配置的<mvc:annotation-driver>注解：配置适配器、映射器
public class SpringMvcConfig {

	@Bean
	public InternalResourceViewResolver getInternalResourceViewResolver() {
		String prefix = "/WEB-INF/pages/";
		String suffix = ".jsp";
		InternalResourceViewResolver res = new InternalResourceViewResolver(prefix, suffix);
		return res;
	}
}

4、web.xml中配置变注解

WebXMLConfig.java

package com.ssm.config;

import java.util.EnumSet;

import javax.servlet.DispatcherType;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration.Dynamic;

import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.filter.CharacterEncodingFilter;
import org.springframework.web.servlet.DispatcherServlet;

/**
 * 该配置类实现WebApplicationInitializer接口，在项目启动时，会执行该类中的onStartup方法
 * 
 * @author wingz
 *
 */
public class WebXMLConfig implements WebApplicationInitializer {

	@Override
	public void onStartup(ServletContext servletContext) throws ServletException {

		// AnnotationConfigWebApplicationContext对象的作用是：把所有的配置类加载到spring容器中
		AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
		context.register(JdbcConfig.class, SpringMvcConfig.class, TxConfig.class);

		// 添加spring核心控制器
		servletContext.addListener(new ContextLoaderListener(context));

		// 配置springmvc前端控制器
		Dynamic servlet = servletContext.addServlet("springmvc", new DispatcherServlet(context));
		servlet.addMapping("*.do"); // 配置拦截所有.do结尾的请求

		// 添加编码过滤器
		javax.servlet.FilterRegistration.Dynamic filter = servletContext.addFilter("encoding",
				new CharacterEncodingFilter("UTF-8"));
		// EnumSet<DispatcherType>：枚举类型，配置过滤器过滤的请求类型
		EnumSet<DispatcherType> dispatcherTypes = EnumSet.noneOf(DispatcherType.class);
		dispatcherTypes.add(DispatcherType.FORWARD);
		dispatcherTypes.add(DispatcherType.REQUEST);
		filter.addMappingForUrlPatterns(dispatcherTypes, false, "/*");
	}

}

注意：使用3.0以后版本的servlet-api.jar，才可以使用注解式的xml

三、测试环境

1、创建表

CREATE TABLE product(
       id varchar2(32) DEFAULT SYS_GUID() PRIMARY KEY,
       productNum varchar2(50) NOT NULL,
       productName varchar2(50),
       cityName varchar2(50),
       DepartureTime date,
       productPrice Number,
       productDesc varchar2(500),
       productStatus number,
       CONSTRAiNT product UNIQUE (id, productNum)
);

2、创建实体类

public class Product {

	private String id;
	private String productNum;
	private String productName;
	private String cityName;
	private Date departureTime;
	private String departureTimeStr;
	private double productPrice;
	private String productDesc;
	private Integer productStatus;
	private String productStatusStr;

3、编写Dao、service、controller层代码以及jsp页面

ProductDao.java

package com.ssm.dao;

import java.util.List;

import org.apache.ibatis.annotations.Select;

import com.ssm.domain.Product;

public interface ProductDao {

	@Select("select * from product")
	public List<Product> findAllProduct();
}

ProductServiceImpl.java

package com.ssm.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.ssm.dao.ProductDao;
import com.ssm.domain.Product;
import com.ssm.service.ProductService;

@Service
@Transactional
public class ProductServiceImpl implements ProductService {

	@Autowired
	private ProductDao productDao;

	public List<Product> findAllProduct() {
		List<Product> list = productDao.findAllProduct();
		return list;
	}

}

PorductController.java

package com.ssm.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.ssm.domain.Product;
import com.ssm.service.ProductService;

@Controller
@RequestMapping("product")
public class ProductController {

	@Autowired
	private ProductService productService;

	@RequestMapping("findAll")
	public String findAllProducts(Model model) {
		List<Product> list = productService.findAllProduct();
		model.addAttribute("list", list);
		return "product-list";
	}
}

product-list.jsp

4、关于时间类型的参数显示以及接受的问题

时间类型的字段在jsp页面显示：

方式1：使用jsp的<fmt>标签

方式2：修改实体类中对应字段的get方法

时间类型的字段在后台接受参数的处理：

方式1：在实体类中的时间类型属性上加入注解：

方式2：在controller中使用注解进行转换

5、
