Today, I will talk to you about what it is like for JavaWeb to develop a campus service system based on ssm. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something from this article.

Using a campus service system developed by Javaweb, it is similar to bounty hunters by publishing their own tasks and setting the amount of reward.

Stuid, studentid, password, schoolid, sex, name, registertime, money, state select from user where stuid = # {stuid,jdbcType=INTEGER} delete from user where stuid = # {stuid,jdbcType=INTEGER} insert into user (stuid, studentid, password, schoolid, sex, name, registertime, money, state) values (# {stuid,jdbcType=INTEGER}, # {studentid,jdbcType=VARCHAR}, # {password,jdbcType=VARCHAR}, # {schoolid,jdbcType=INTEGER}, # {sex,jdbcType=INTEGER}, # {name,jdbcType=VARCHAR}, # {registertime,jdbcType=TIMESTAMP}, # {money,jdbcType=DOUBLE} # {state,jdbcType=INTEGER}) insert into user stuid, studentid, password, schoolid, sex, name, registertime, money, state, # {stuid,jdbcType=INTEGER}, # {studentid,jdbcType=VARCHAR}, # {password,jdbcType=VARCHAR}, # {schoolid,jdbcType=INTEGER}, # {sex,jdbcType=INTEGER}, # {name,jdbcType=VARCHAR}, # {registertime,jdbcType=TIMESTAMP}, # {money,jdbcType=DOUBLE}, # {state,jdbcType=INTEGER} Update user studentid = # {studentid,jdbcType=VARCHAR}, password = # {password,jdbcType=VARCHAR}, schoolid = # {schoolid,jdbcType=INTEGER}, sex = # {sex,jdbcType=INTEGER}, name = # {name,jdbcType=VARCHAR}, registertime = # {registertime,jdbcType=TIMESTAMP}, money = # {money,jdbcType=DOUBLE}, state = # {state,jdbcType=INTEGER}, where stuid = # {stuid,jdbcType=INTEGER} update user set studentid = # {studentid,jdbcType=VARCHAR}, password = # {password,jdbcType=VARCHAR}, schoolid = # {schoolid,jdbcType=INTEGER}, sex = # {sex JdbcType=INTEGER}, name = # {name,jdbcType=VARCHAR}, registertime = # {registertime,jdbcType=TIMESTAMP}, money = # {money,jdbcType=DOUBLE}, state = # {state,jdbcType=INTEGER} where stuid = # {stuid,jdbcType=INTEGER} SELECT from `user`WHERE CONCAT (studentid,name) LIKE # {words,jdbcType=VARCHAR} SELECT COUNT (*) FROM `user`WHERE studentid = # {account,jdbcType=VARCHAR} SELECT FROM `user`WHERE studentid = # {account,jdbcType=VARCHAR}
