2.项目基础配置
找到maven工程所在目录下org.eclipse.wst.common.project.facet.core.xml此文件
修改成如下内容
maven工程下的web.xml文件替换为
pom.xml文件中修改build节点,添加如下内容
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.1</version> <configuration> <source>1.7</source> <target>1.7</target> </configuration> </plugin>
3.在pom.xml追加如下内容
org.mybatis.generator
mybatis-generator-core
1.3.2
org.mybatis.generator
mybatis-generator-maven-plugin
1.3.2
src/main/resources/generatorConfig.xml
true
true
MySQL
mysql-connector-java
5.1.34
Generate MyBatis Artifacts
generate
4.在src/main/resources文件下创建generatorConfig.xml,内容如下
5.右键项目--》run As--》Maven build--》输入mybatis-generator:generate,即可创建成功。
6.生成代码如下
package com.lymn.it.mapper;
import com.lymn.it.model.User;
public interface UserMapper {
int deleteByPrimaryKey(Integer userid);
int insert(User record);
int insertSelective(User record);
User selectByPrimaryKey(Integer userid);
int updateByPrimaryKeySelective(User record);
int updateByPrimaryKey(User record);
}
userid, username, password, email, phone, status, code
delete from user
where userid = #{userid,jdbcType=INTEGER}
insert into user (userid, username, password,
email, phone, status,
code)
values (#{userid,jdbcType=INTEGER}, #{username,jdbcType=VARCHAR}, #{password,jdbcType=VARCHAR},
#{email,jdbcType=VARCHAR}, #{phone,jdbcType=VARCHAR}, #{status,jdbcType=VARCHAR},
#{code,jdbcType=VARCHAR})
insert into user
userid,
username,
password,
email,
phone,
status,
code,
#{userid,jdbcType=INTEGER},
#{username,jdbcType=VARCHAR},
#{password,jdbcType=VARCHAR},
#{email,jdbcType=VARCHAR},
#{phone,jdbcType=VARCHAR},
#{status,jdbcType=VARCHAR},
#{code,jdbcType=VARCHAR},
update user
username = #{username,jdbcType=VARCHAR},
password = #{password,jdbcType=VARCHAR},
email = #{email,jdbcType=VARCHAR},
phone = #{phone,jdbcType=VARCHAR},
status = #{status,jdbcType=VARCHAR},
code = #{code,jdbcType=VARCHAR},
where userid = #{userid,jdbcType=INTEGER}
update user
set username = #{username,jdbcType=VARCHAR},
password = #{password,jdbcType=VARCHAR},
email = #{email,jdbcType=VARCHAR},
phone = #{phone,jdbcType=VARCHAR},
status = #{status,jdbcType=VARCHAR},
code = #{code,jdbcType=VARCHAR}
where userid = #{userid,jdbcType=INTEGER}
package com.lymn.it.model;
public class User {
private Integer userid;
private String username;
private String password;
private String email;
private String phone;
private String status;
private String code;
public Integer getUserid() {
return userid;
}
public void setUserid(Integer userid) {
this.userid = userid;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username == null ? null : username.trim();
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password == null ? null : password.trim();
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email == null ? null : email.trim();
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone == null ? null : phone.trim();
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status == null ? null : status.trim();
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code == null ? null : code.trim();
}
}
8.参照SSM框架搭建之传统方式(一)博客中的service、controller层进行测试
