實現table的分頁，如果查詢的數據是多表查詢，分頁查詢時只有第一頁，解決方法：可以對查詢的數據正常分頁，再寫個SQL語句查詢數據總個數
配置：SqlSessionFactoryBean中
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="typeAliasesPackage" value="com.jsqj.regcontrol.bean">
</property>
<!-- 傳入PageHelper 分頁插件 -->
<property name="plugins">
<array>
<!-- 傳入插件的對象 -->
<bean class="com.github.pagehelper.PageInterceptor">
<property name="properties">
<props>
<!--數據庫類型-->
<prop key="helperDialect">mysql</prop>
<!--頁碼超出範圍自動修正-->
<prop key="reasonable">true</prop>
</props>
</property>
</bean>
</array>
</property>
</bean>
不使用maven，需要添加jar包（版本根據情況）
jsqlparser-1.0.jar
pagehelper-5.1.4.jar
demo結構
DAO層：
public class Student {
private String id;
private String name;
private Integer age;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id == null ? null : id.trim();
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name == null ? null : name.trim();
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
}
**mapper層;**
public interface StudentMapper {
List<Student> selectAll();
int count();
}
**service層**
public interface StudentService {
List<Student> selectAll(Integer pageNum,Integer pageSize);
int count();
}
**serviceImpl層**
@Service
public class StudentServiceImpl implements StudentService {
@Autowired
private StudentMapper stu;
@Override
public List<Student> selectAll(Integer pageNum,Integer pageSize) {
PageHelper.startPage(pageNum,pageSize);
List<Student> students = stu.selectAll();
return students;
}
@Override
public int count() {
return stu.count();
}
}
**controller層**
@RestController
@RequestMapping("/findAll")
public class FindAll {
@Autowired
private StudentServiceImpl stu;
/**
* layui中table表分頁，默認是page=1，limit=10，與pagehaper參數對應，
* layui中還需要數據的總個數count
* @param pageNum
* @param pageSize
* @return
* @throws Exception
*/
@ResponseBody
@RequestMapping("/student")
public String student(@RequestParam("page") Integer pageNum, @RequestParam("limit") Integer pageSize) throws Exception {
List<Student> students = stu.selectAll(pageNum, pageSize);
int count = stu.count();
JSONObject json = new JSONObject();
json.put("code", 0);
json.put("count", count);
json.put("data", students);
return json.toString();
}
}
**xml文件**
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
