package com.liuhai.eshop.dao;
import java.util.List;

UserService.java 用户service层接口如下：
package com.liuhai.eshop.service;
import java.util.List;
import java.util.Map;
import com.liuhai.eshop.domain.User;
public interface UserService {
public List getAll();
public User getUser(User user);
public int delete(int id);
public int update(User user);
public int add(User user);
public List find(Map map);
public Long getTotal(Map map);
public User getUserById(int id);
}
UserServiceImpl.java 用户service实现层如下：
package com.liuhai.eshop.service.impl;
import java.util.List;
import java.util.Map;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.liuhai.eshop.dao.UserDao;
import com.liuhai.eshop.domain.User;
import com.liuhai.eshop.service.UserService;
@Service(value="userService")
public class UserServiceImpl implements UserService {
private UserDao userDao;
@Resource
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
@Override
public List getAll() {
return userDao.getAll();
}
@Override
public User getUser(User user) {
return userDao.getUser(user);
}
@Override
public int delete(int id) {
return userDao.delete(id);
}
@Override
public int update(User user) {
return userDao.update(user);
}
@Override
public int add(User user) {
return userDao.add(user);
}
@Override
public List find(Map map) {
return userDao.find(map);
}
@Override
public Long getTotal(Map map) {
return userDao.getTotal(map);
}
public User getUserById(int id){
return userDao.getUserById(id);
}
}
user实体类如下：
package com.liuhai.eshop.domain;
import java.io.Serializable;
/**
* 用户实体
* @author Administrator
*
*/
public class User implements Serializable{
private static final long serialVersionUID = 1L;
private Integer id;
private String userName;
private String password;
private Integer age;
private String trueName;
private String email;
private String phone;
private String roleName;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getTrueName() {
return trueName;
}
public void setTrueName(String trueName) {
this.trueName = trueName;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getRoleName() {
return roleName;
}
insert into users values(null,#{userName},#{password},#{age},#{trueName},#{email},#{phone},#{roleName})
delete from users where id = #{id}
update users
age = #{age},userName = #{userName},password = #{password},trueName = #{trueName},email = #{email},phone = #{phone},roleName = #{roleName},
where id = #{id}
六、创建测试类，测试数据源是否通了
以上spring框架及spring+mybatis配置基本完成，再就是创建测试类测试数据源是否通
首先创建一个mysql库的，再建立users表，创建测试类TestSpring.java如下：
package com.liuhai.eshop;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.liuhai.eshop.domain.User;
import com.liuhai.eshop.service.UserService;
public class TestSpring {
@Test
public void TestUserService() throws Exception{
@SuppressWarnings("resource")
ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");
UserService us=(UserService) ac.getBean("userService");
User user=new User();
user.setAge(1);
user.setUserName("zhangsan");
user.setPassword("123456");
user.setTrueName("张三");
us.add(user);
}
}
web 测试页面contextConfigLocationclasspath:applicationContext.xmlencodingFilterorg.springframework.web.filter.CharacterEncodingFiltertrueencodingUTF-8encodingFilter/*org.springframework.web.context.ContextLoaderListenerorg.springframework.web.util.IntrospectorCleanupListenerspringMVCorg.springframework.web.servlet.DispatcherServletcontextConfigLocationclasspath:spring-mvc.xml1truespringMVC*.dodefault*.cssdefault*.gifdefault*.pngdefault*.jpgdefault*.js/index.jsp
1. 创建一个maven项目
2. 创建com.CoberturaStart.java
package com;
public class CoberturaStart {
public void helloEveryone(){
System.out.println("=================================================
我并不知道出现这个问题的实际原理,只是通过其他朋友的博客,文章得知的一个解决方案,目前先记录一个解决方法,未来要是真了解以后,还会继续补全.
在mysql5中有一个safe update mode,这个模式让sql操作更加安全,据说要求有where条件,防止全表更新操作.如果必须要进行全表操作,我们可以执行
SET
public class DeleteSpecificChars {
/**
* Q 63 在字符串中删除特定的字符
* 输入两个字符串，从第一字符串中删除第二个字符串中所有的字符。
* 例如，输入”They are students.”和”aeiou”，则删除之后的第一个字符串变成”Thy r stdnts.”
